The Motley Fool's CAPS investing service is one of the newest additions to the investing community at Fool.com, and it's another great way for investors to work together to beat the market. One of the features in CAPS allows users to set up a blog to talk about their picks, investing strategy, market view, or favorite rugby team (if that's what floats their boat).

Now that CAPS blogging has caught on, there's a lot of great content being added on a daily basis. So I've decided to dig through all of the blog posts over the past week to bring you some of the best. There's no way I could hit all of the great stuff in the CAPS blogosphere -- I cover only seven posts here -- so when you're done with this article, I highly recommend checking out some more on your own.

Community intelligence works
The bottom line of the social stock-picking experiment we call CAPS, of course, is to find out whether CAPS can actually help investors find good investment opportunities, and whether five-star stocks (the highest CAPS rating possible) such as Cemex (NYSE:CX), on average, outperform the market. With a year of data behind CAPS now, it's possible to start taking a look at that bottom line.

On his CAPS blog, TMFBreakerDave, a.k.a. Fool co-founder David Gardner, takes a look at what that data shows. I could tell you what his conclusion is, but then you'd miss out on the cool charts he has in his blog!

CitiBank of America
Is JR10022's fictitious blog post about a future merger between Bank of America (NYSE:BAC) and Citibank (NYSE:C) just a bit of fun, or is it a foreshadowing? What I can say for sure is that it's darn funny. As for what the future holds -- let's just say that if it's anything like JR's picture, Ken Lewis may be one of the only people smiling.

CAPSCenter: Shorting with the Pork Mogul
In this week's edition of CAPSCenter, TMFHollywoodDan discusses the art of the short (betting against a stock) with TMFBBQPorkMogul. As a bonus, Dan also managed to wrangle an appearance from Dr. Hans Jaab, a professor with an uncanny resemblance to another CAPS player, the intractable TheDukeofWallSt.

And while we've got Dan in the spotlight, you might want to also head over to his more recent blog post, in which he addresses the shareholders in his CAPS fund.

New builder rankings
In a recent blog post, CAPS All-Star floridabuilder revisited the rankings he made for the major public builders three months ago. Though the industry has been clobbered, his picks seemed to be pretty much on the money -- his top picks lost far less than did the builders he thought were potential bankruptcy candidates.

In his blog post, he also delivers a new set of builder rankings for the next three months. Though he ranked Pulte Homes (NYSE:PHM), Ryland (NYSE:RYL), and Lennar (NYSE:LEN) as sells, he highlighted four homebuilder stocks that are worthy of a "hold" rating -- the highest he's willing to hand out right now for this industry. The lucky four? Well, you'll have to visit his post to find out!

First Solar math
It would be hard to wipe the smile off the face of a First Solar (NASDAQ:FSLR) shareholder, after the year the stock has had. But will the big gains continue? Though he doesn't think shorting the stock would be particularly prudent, top CAPS player StatsGeek is also pretty convinced that today's price is not sustainable in the longer term.
