Yesterday, we uncovered Rating Burner, a new site that ranks popular blogs by their total subscribers, as calculated by FeedBurner. The site, previously unknown to the blogosphere, offered little behind its story, and little clue to its owner, though we did find Alexander Fedorov as the registrant of ratingburner.com. Today, Alexander emerged, and sent me a few e-mails, which further explained the site's origin and purpose, uncovering an interesting approach to discovering new sites and RSS feeds, as well as Web advertising opportunities.

First off, the site is more than an Internet egotist's dream. Rating Burner has its own Web crawler, aimed to discover new FeedBurner feeds and subscriber counts. As Fedorov wrote today, "The rating is growing all by itself. As soon as someone links to your blog, sooner or later it will be found by Rating Burner's bot."

And the bot had to start somewhere. Fedorov kicked off the Web crawling using John Battelle's Searchblog at http://battellemedia.com/. You can see this by using the same type of URL hacking popularized with ReadBurner just yesterday. Try the URL http://www.ratingburner.com/?order=1&dir=a and find the exact order of the robot's work. Hovering your mouse over the "1" in the "N" column shows the site was indexed by January 18th at 11:18 a.m. 4 minutes later, it was off to the Black Hat SEO Diary. 3 minutes later, the robot found TechCrunch, and it was off to the races. The robot eventually found louisgray.com on January 20th after noon, making me #216 in the list, which now has 368 individual sites.

Even more interesting, Rating Burner shows a detailed map of how each of these blogs link to one another. (Download the detailed graphic) The sites with the most links their way have the most arrows, and those sites with the most FeedBurner subscribers have the widest arrows to and from their site. As the below graphic shows, his robot correctly noted I link out to Mashable and WinExtra links to me. The map was generated by GraphViz, an open source tool.


My position in Rating Burner's map.
The robot spawned by Rating Burner has specialized intelligence to discover ad networks, and enables site owners to display going rates. As Alexander explains, the "crawler scans all blogs for signatures of some well known sponsors/advertisers and lists this information. It is possible to publicize prices for banner ads using special html comment . Crawler will find this info and publish price in the rating."

There are also a number of hidden tricks in the database.

To find out the total number of comments in the most-recent post on any included blog, you can sort with the below URL:
http://www.ratingburner.com/?order=17

To sort included sites by the most recent post, it's a different command:
http://www.ratingburner.com/?order=16

... and by PageRank:
http://www.ratingburner.com/?order=12

If you recall, Rating Burner also hinted at further categorization, including tags for SEO and gadgets. Alexander promises there are many more to come, automatically generated, again by the robot and the intelligent database:

He writes, "...categorization is completely automated. I have several samples of texts on special subjects like "gadgets" and then all blogs (5 last posts) are tested againts this texts using bayesian filter and shingles, and if the similarity is close enough, this blog will be listed under this category. I just need to add more categories and collect more sample texts."

Rating Burner is still in its infancy, even after yesterday's debut, without question. But there are some interesting tricks lurking in the database. Want to find recent posts with lots of comments that might be "hot"? Try this link: http://www.ratingburner.com/?order=4&filter=category%3ATOP.

And the blogosphere has noticed. In addition to my post, which hit TechMeme, and Mashable's coverage this morning, the site's debut was included in Danny Sullivan's Search Engine Land wrap-up for the day, as well as Marketing Pilgrim.

Some companies will talk about change, and not follow through. Mashable is not one of them. After promising to offer an improved level of transparency and attribution, the popular social networking news site has done exactly that, revamping they way they report news, share linkage and introduce original sourcing. Over the last few weeks, Mashable has managed to seamlessly keep reporting the news while adapting to the new guidelines... and that's hard to do.

With that said, I wanted to draw your attention to three great stories Mashable is running right now.

Readburner’s Unofficial API
http://mashable.com/2008/01/31/readburner-api/

Hardly a day goes by without Alexander Marktl's pet project, ReadBurner, making the news. Yesterday, as noted in my link blog, David Rothman posted a piece on Hacking ReadBurner URLs, which can deliver unique, and often unexpected, results. URL hacking is among my favorite past-times. Combine it with ReadBurner, and you've got some good fun ahead.

RatingBurner Ranks Blogs According To RSS Numbers
http://mashable.com/2008/01/31/ratingburner-ranks-blogs-according-to-rss-numbers/

Mashable's Stan Schroeder also followed up on our piece on Rating Burner from last night, highlighting the new site's ability to rank blogs by RSS numbers. As he writes, "... it’s a ranking system with positive sides and flaws like any other, and I guess it can’t hurt to have another one."

All are worth clicking through and reading. Make sure you do. And Mashable, nice job.

There's precious little that bloggers like to do more than measure their own statistics, and gauge how they're doing, relative to the rest of the blogging community. And there's similarly precious little that smart Web developers like to do than harness publicly available data, point it at an intelligent database, and debut a new service.

When the two come together as one, you have the potential for a must-bookmark site that stataholics and egotists alike will visit time and again.

While earlier this month, we talked about two new sites focused on tabulating popular shared links from Google Reader, in ReadBurner and Shared Reader, today we've seen a new, unheralded site emerge, which displays the most popular blogs, by RSS feed subscribers, and shows their day to day momentum in terms of new subscribers or defectors. That site's name, appropriately enough, is Rating Burner.

(Note: There are no blog hits for Rating Burner as of 8 p.m., but the secret is now out!)

Though in its early stages, Rating Burner is accomplishing what many geeks set out to do by hand just a few short months ago. (See: Top Blogs On Google Reader, How Many Google Reader Subscribers Do You Have? and Find the Number of Google Subscribers for Any Feed)

The site, currently holding approximately 400 individual blogs and RSS feeds, at time of this posting, aims to summarize a blog's feed popularity, show its Google PageRank (a measurement often used to illustrate trust), its aggregate change in subscribers over the previous 24 hours, including percentage change, when they most recently posted, and what, if any, ad services they use.


The Most Popular Blogs, According to Rating Burner
While the list isn't yet 100 percent inclusive, Rating Burner unsurprisingly shows TechCrunch, the official Google Blog, Mashable and Guy Kawasaki among the top-subscribed feeds. Amazingly, Rating Burner shows more than 11,000 new adds to TechCrunch's 654k subscriber army in the last day alone, dwarfing the 709 Mashable picked up, and my measly 38, although I did manage to go up more than 8 percent between the two snapshots.

As with ReadBurner, Rating Burner should only get better with time, and with user submissions of new blogs. The site offers an entry form to post new blogs for inclusion, and looks like it will soon add categories, to further segment the data. So far, the site has SEO blogs and Gadget blogs listed as possible filters.

Also like ReadBurner, upon initial writeup, Rating Burner's UI is quite spartan, but the functionality is very interesting. I'm impressed to see the developer has grabbed the FeedBurner statistics for each blog and is hosting the results on their site, rather than externally pointing to FeedBurner graphics. I for one noted the statistics listed for louisgray.com were from Monday night, so it's likely the data trails by a full 24 hours. Thanks to my subscriber count dropping from 436 to 413 overnight, I would expect my own stats to drop tomorrow, reflecting Tuesday's data.


louisgray.com, 37th fastest-growing, according to Rating Burner
If you would like to be included in Rating Burner, post your blog feed at their URL, and they will likely index you for tomorrow's results. While I used the site's contact us form on their Web site to reach the developer, I haven't yet heard back, and we don't yet know for certain the individual behind the service. Domain name records show Rating Burner registered to Alex Fedorov in Massachusetts, so we hope to hear from him soon and see the service further develop.

Since early last year, when Steve Rubel of Micro Persuasion introduced me to iPings, I've relied on the multi-service Ping engine to update sites including Technorati, Weblogs.com, FeedBurner and IceRocket, alerting the services that my blog had been updated. Using a simple form, I could enter my data in iPings and hit all the services at once, rather than updating them individually, or hoping their spiders were quick.

But for this entire week, iPings has gone missing, offering instead a stark notice, saying, "ipings.com is down for maintenance. We apologize for any inconvenience this may have caused. Please check back soon."

But unlike Twitter, which goes down for maintenance seemingly a few times a day, iPings has never come back up, and it's tempting to think the service just might be gone - leading me to use my backup, Pingomatic, or trust the Web crawler gods.

While iPings never sported the most creative of Web layouts, and often annoyed with flashing banner ads or unreadable captchas, it simply got the job done. Now, I have to wonder if they're all done too.
