The Motley Fool's CAPS investing service is another great way for investors to work together to beat the market. Among other features, CAPS lets users blog about their picks, investing strategy, market view, favorite rugby team, or whatever floats their boat.

As CAPS blogging catches on, players add more great content on a daily basis. I've dug through the past week's posts to find some of CAPS' best insights. With room for only seven posts here, I can't possibly cover all of the great stuff in the CAPS blogosphere. When you're done here, I highly recommend checking out some more.

Circuit City: Icahn Hears a Who!
If a title like this doesn't catch your attention, you're probably asleep at your desk. The saga of Circuit City (NYSE:CC) continues, with everyone's favorite billionaire investor Carl Icahn now joining Blockbuster (NYSE:BBI) in hot pursuit of the electronics chain. Why so much interest in the poor man's Best Buy (NYSE:BBY)? Check out btown819's blog for his take on the situation.

Medical suppliers poised for growth
As the credit crisis spreads its tendrils out into the economy, many sectors are feeling the pain.

Thoughts from the 1981 Berkshire letter to shareholders
This year, Warren Buffett made plenty of news by saying that investors needed to lower their expectations regarding the kind of returns they'll receive from Berkshire Hathaway (NYSE:BRK-A) (NYSE:BRK-B) shares. As JDSancho points out, this isn't anything new for Warren -- he's been keeping expectations in line for a long time. Check out JD's blog for his take on Warren's proclamation.

Best little warehouse in Texas
Ok, I'll admit that I first opened this blog because of the catchy title. (Ever seen that great Burt Reynolds movie?) However, I found LouieJunior's post about a warehouse that belongs to (NASDAQ:AMZN) surprisingly interesting -- particularly given the company's recent tussle with New York state over tax laws. Check out Louie's blog for the scoop.
