Monitoring Social Networks

If you're at all interested in the social, economic and technological growth of social networks and Facebook specifically, I'm going to recommend you add these blogs to your Google Reader (which you should already be using).

• AllFacebook - As far as I'm concerned, Nick O'Neill runs your one-stop shop for monitoring the progress of Facebook. His commentary is concise and precise, and his occasional recommendations have proven useful.
  
• Facebook-Developer - A more technical analysis of the progress of the Facebook Platform for Application development. Emphasizes strong, structured, portable coding practices and keeps us all up to date on the scattered-at-best Facebook Development knowledge base.
• InsideFacebook - The first resource for a lot of Application developers back in August/September, InsideFacebook tends to get excited mostly about the financial potential of Applications and Facebook itself.
• Facebook Developers News Feed - If you're at all interested in developing your own Application, you're going to need to keep an eye on the official Facebook developer blog. Not updated often, but their authoritative declarations of changes to your development tools makes them sometimes feel like the Alan Greenspan of Facebook.
• TechCrunch - Not devoted to Facebook specifically, TechCrunch is IMO the place to see what technology is making a buzz out in Silicon Valley. They monitor big venture capital investments for startups, and watching the money is a good practice to understand the direction social networking will take.

That should tide you over until your first Application reaches 100,000 installs. Enjoy!
