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, so when you're done here, I highly recommend checking out some more.

Jon Stewart and the economy

No social stigma for foreclosure
Though the Federal Reserve's aggressive interest-rate cuts have somewhat alleviated the pain of plummeting lenders such as Countrywide (NYSE: CFC) and Bank of America (NYSE: BAC), the fall has been nonetheless drastic. CAPS All-Star InvestorDeb offers an interesting take on the rash of real estate defaults that have been putting so much pressure on lenders. She laments the disappearance of relationship banking, in which the borrower and the ultimate lender actually sat across the table from each other and there was still some stigma attached to reneging on an agreement to pay back a loan.

Market calls all over the place
If the volatility of the financial markets lately hasn't convinced you that nobody really knows what's going on, then I highly suggest that you check out this blog post from QualityPicks. He sums up the sentiments of a variety of market gurus which are -- you guessed it -- all over the place.

Sector on fire!
Has TMFSarahGen found a ready-to-surge industry that you've missed? Check out her blog post to find out, but I'll give you a hint -- if she's right, Ethan Allen (NYSE: ETH) stands to continue surging.

Builder alert!
Doggone it! Just when it looked as though our resident builder expert floridabuilder was getting positive on a few homebuilders, Centex (NYSE: CTX) has to go and screw it up for everyone. According to floridabuilder, things have gotten much worse. In another post, he even gave up on some of his favorites, including NVR (NYSE: NVR) and KB Home (NYSE: KBH).

Why look at the depression?
The airwaves have been overrun with Chicken Littles lately. I don't think our financial system is unraveling, and I hardly think the Federal Reserve is being grossly negligent. But I can't deny that there is another side to the story, nor can I say that the arguments from that side are completely without basis. For some thoughts on how badly things could end up, check out dwot's blog.

The "typical" investor
Need a breather after pondering this potential move into depression conditions? Check out camistocks' blog. Though it may not paint the prettiest picture of the "typical investor," it shows why being a Fool is a good thing, and it's certainly good for a laugh.

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