It's more than Silicon Valley legend that if you find the right misguided tech shop, you can sometimes purchase items before their manufacturer wants them released. Whether its a game console, like Microsoft's XBox 360 Arcade, or an operating system, the retail shops just might not know or might not care.

On my way home this evening, I had a hunch that the Fry's superstore here in Sunnyvale would be one of those shops. Fry's is notorious for either putting an item on a shelf with no fanfare (the situation when I bought my wife a 2nd gen iPod Shuffle on the 2nd day it was available), or just flat-out not having an item at all, weeks after its debut. It's a serious hit or miss.

While I've already made up my mind that I'd like to hit up an Apple retail store tomorrow and be there for Leopard's unveiling, if I could get my hands on Leopard a day early thanks to Fry's, I would have purchased it tonight. But, no such luck. As I bee-lined my way to the Mac section of the store, they were all too prepared for geeks like me, with signs saying Leopard would be available for sale not today, but tomorrow, at 6 p.m. There wasn't even a box in sight. If there were, I would of course have played dumb and walked it up to the front register with intent to take it home.

So, I left the store empty-handed. I guess I'm not a real geek if I could get into Fry's and leave without buying anything, but today I'm willing to have that shame. Tomorrow however, is Leopard day. Meow.

I've long been a Google Reader and Google Reader shared items link blog advocate. The service lets me call out to you what I'm reading in the blogosphere, and what I find interesting. But for me, and for many other people using a wide variety of Web 2.0 applications, my link blog only covers one facet of my activity.

Where Google leaves off, Friendfeed steps in, combining my updates from around the Web, not only from Google Reader, but also noting when I update louisgray.com, when I add new items to del.icio.us, when I Digg new stories, find something via StumbleUpon or add photos to Flickr. Others also use it to display their activity on Twitter and Pownce. This creates a feed for not just one facet of my activity, but many.

That answers the "feed" portion of Friend feed. But the "Friend" portion takes the service up a notch. I can subscribe to friends and watch their activity one by one, or go to a combined "Friends Feed" and see all their combined activity. From this page, I can see if MG Siegler Dugg a story, if Fred Wilson added a new post to his blog, or if Jeremy Zawodny added a new bookmark to his del.icio.us items. It's a lot like reading Robert Scoble's shared link blog, but one written by multiple people, and with more sources.

The site is currently in beta, and ramping up, having been started by a few notable ex-Googlers, looking to gain traction as the service goes viral. Their blog shows their new office space, as they're just getting started.

My feed is here. If you need an invitation to the service, just say so in the comments, and I'll send it via e-mail.

Given how much personal information and business relationships are exposed on social networks like Facebook and LinkedIn, I'm continually surprised that I see so little activity from the news media utilizing the updates each of those services bring. If I were a reporter, I would want to "Link In" to as many potential news sources as I could to companies I found relevant, and I would watch their activity to gain early insight into partnerships, promotions, and comings and goings.

As the use of LinkedIn grows in a wide variety of markets, not just those in technology, one can also gauge company size and growth relative to its peers by the total number of employees using the service. While it's not scientific, as one company's LinkedIn penetration can vary widely from the next, it's a good rule of thumb.

Example:

Current Company = Facebook: 191 records
Current Company = MySpace: 403 records
Current Company = SmugMug: 12 records

If I were a reporter linked in to spokespeople, management or even the PR flacks at a company, I would watch for "Profile Updates" that showed changes in title or responsibility, or if they had left one firm for another. I could see if that person had added a new connection - possibly to a new hire, or signifying a new partnership or customer. I could even do a search to see how often companies showed up as having been where someone had previously worked, but no longer does. If more people formerly worked for a company than are still there, would that signal unrest or a layoff? A good reporter could put two and two together to get the answers.

ValleyWag shows a great example of this, where they found Facebook and Microsoft "making friends" before the companies' announced investment.

Just within my own LinkedIn network, I can get early alerts showing people's changing career path. I've seen people become friends with customers or partners before their announcements hit the press wire. Often, by the time the media gets it, the story has had weeks or months to bake.

Want to know what's going on at the latest company in "stealth mode"? Search for their name, and see who they're hiring. Where did they come from? How many employees do they have? LinkedIn just might have the answers.

In a world where more data is becoming transparent, LinkedIn is a killer resource to gain information on industries, companies and competition. Reporters who figure it out and use it to the best of their ability will be a step ahead of everybody else.

In what many readers here will no doubt see as a positive development, Michael Arrington of TechCrunch announced the popular blog will no longer link the names of companies they cover to the CrunchBase, the network's internal database on company information and resources.

As he wrote in a post today:

"We started linking to CrunchBase often in our posts. This tends to drive some readers absolutely nuts because they want to go to the company, not CrunchBase, when they click a link. As of today that policy is being discontinued."

I've been a vocal advocate for clarity in linking practices, and generally dislike unnecessary internal linking. Though I didn't call out TechCrunch for this practice, many here did in our previous discussions of common behavior from leading tech blogs.

Arrington and his blog network, despite the occasional criticism, have done excellently well at making a name for themselves, and becoming one of the leading resources for Web 2.0 information and news. I applaud this move, and hope that others will look to the leader and follow suit.
