In late January, we first discussed RatingBurner (www.ratingburner.com), an interesting entry in the market, which helped rank blogs by their number of public FeedBurner RSS subscribers, and showed their day to day growth, both in aggregate numbers, and percentage increase. While Alexander Fedorov has been a little quieter than some other new entrants in the Web sphere, he has continued to update the site, adding new blogs daily, and inserting new features - including the debut of a new widget, which bloggers can use to show where they rank in RatingBurner's current standings.While the value of ranking sites by their RSS count is the subject of some debate, in the absence of public, uncontested traffic and return visitor data, it is one metric available to nearly all major blogs, especially as FeedBurner has become the online standard for RSS delivery and tracking.
In the last few months, Fedorov wrote me to say, first, that support for branded feeds (i.e. not from feedburner.com) was added, and that feeds which point to subdomain of a blog but are still published with FeedBurner, can be added.
This might sound like a minor change, but this enabled sites like Engadget to be included. Engadget, which didn't figure in the first screen capture, now shows 1.6 million RSS readers, and even minute swings can show adds and drops of thousands per day. From January through today, you can also see TechCrunch increased from 654,000 readers to 782,000, and Mashable from 143,000 to 167,000.
As for me, at the time I clocked in with that post, I had 436 readers, and we're now seeing FeedBurner report 1,028 total.
Last week, Fedorov added a button for bloggers to post on their own site. As he wrote, the "button will automatically show a blog's ranking and when you click on it, you will be redirected exactly where they are sitting in the ranking."For fun, I added mine to the site, and you can see my ranking (in the 400s) on the right side of louisgray.com. Does it add a ton of value? Not a lot, especially as you can consider to Rating Burner doesn't have the entire blogosphere indexed. But the database has grown dramatically since it first showed up in January, and it's always fun to see where you sit against your peers and competition, so if you're so inclined, it's real simple to add the button to your template. You can find out how on the RatingBurner Web site.
At the end of 2007, 
The site bills itself as "a social news service that connects people with personalized news and information".The site's main hubs are its "News Networks", which are user created, whether on tech topics, including Apple, Web 2.0, Tech News or Venture Capital, or other interests, from History to Team Building and Triathlons. Users can join any number of news networks, effectively subscribing to view posted news on topics they find interesting. Some of the networks are quiet, seeing only five stories a day, while those more broad topics can see hundreds of new items in a 24-hour period.
There are two ways to add content to Social|Median, the first being a Twitter-like "Snip", where you can post your thoughts on any topic, or a "Clip", where you can post a headline, a URL to the story and any comments you have. Interestingly, Social Median does the hard work of using its algorithm to determine what are the appropriate news networks for your story, based on the submitted content, and that story can be listed in more than one network at a time.
There are two major trends converging in the blogosphere. The first is the growth of sites dedicated to tracking shared items, and the second is, as Allen Stern from CenterNetworks called it, 


"Imagine a site like Digg where the entire community is made up of readers and fans of louisgray.com. But this is not an isolated community. Nope, BlogRize is an integrated site of many separate but interconnected blog "channels". So, there is not going to be a problem of the content stagnating due to a certain channel having a small subscriber base. In fact, our system is able to generate a HOT page of highly relevant links within a channel - even if that channel has zero subscribers. It can do this because it knows what keywords and what other blogs are most relevant to louisgray.com."
Not being one of the Silicon Valley elite, I've always had a soft spot for "the little guy".
