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 strategies, market views, favorite rugby teams, and whatever else floats their boat.

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

New track players in CAPS
As many CAPS players know, CAPS tracks the performance of investment banks and stock pickers, like Jim Cramer, so investors can measure themselves against some of the pros. Now there are more pros to compete against. In a recent update to CAPS, a group of some of the top portfolio managers and investors was added to the mix. Among the group are Berkshire Hathaway's (NYSE: BRK-A) Warren Buffett and Legg Mason's (NYSE: LM) Bill Miller. For more details, check TMFCHarris' blog.

Calling Buffett a liar
Speaking of Warren Buffett, was he lying when he said the U.S. is in a recession? Gtrinvestor takes a look at the assertion by James Altucher of TheStreet.com that Buffett was lying to push the market down. Altucher noted that Buffett and Berkshire Hathaway have $50 billion in cash to put to work, and lower stock prices would help Buffett out.

Quarterly builder rankings
In this terrific post, CAPS All-Star floridabuilder revisits his previous rankings of public builders to see how they've performed, and he runs through his updated rankings. NVR (NYSE: NVR) and Toll Brothers (NYSE: TOL) both stayed in the top tier, but they were joined by a couple of surprising picks. Click to floridabuilder's blog to get the scoop.

Huge dividend + valuable assets + hated sector = buy!
What stock is TMFDeej referring to in this intriguing title? It's Canadian oil trust Penn West Energy Trust (NYSE: PWE). Check Deej's blog to find out why you should consider owning this high-yielding stock.

Get on board the Apple bandwagon -- now!
CAPS blogger JJMSpartan thinks that now is the time to buy shares of Apple (Nasdaq: AAPL). In his post he gives his case for Apple stock as an outperformer, and in particular, focuses on the imminent upgrade to the iPhone. Spartan thinks the new enterprise compatibility of the iPhone will do big things for sales, and was impressed by the demonstrations done by Salesforce.com (NYSE: CRM) and other outside developers.

$300 billion
CAPS blogger VTEngineer2001 notes that the war in Iraq is costing around $300 billion per year. What else could we do with $300 billion? Glad you asked! VTEngineer examines just that in this post.

And that's our roundup for the week. Be sure to check back next week for more blogging action. In the meantime, why not head to CAPS and add your two cents to the community pool?
