The Motley Fool's CAPS investing service is another great way for investors to work together to beat the market. Among other features, CAPS gives users blogs to discuss their picks, investing strategy, market view, or favorite football team (if it floats their boat).

As our players take to CAPS blogging, a lot of great content has begun appearing every day. I've dug through all of the blog posts over the past week to bring you some of the best posts CAPS can offer. The mere seven posts I've got room for here can't do justice to all the great stuff in the CAPS blogosphere. So when you're done here, I highly recommend checking out more of our players' opinions.

We're doomed!
Big banks like Wachovia (NYSE:WB) are writing down huge amounts, the markets have been all over the place, and even Google (NASDAQ:GOOG) has recently been selling off. What's an investor to do?

In his recent blog post, Hoglum suggests that long-term investors' lives don't need to be drastically derailed in times of market uncertainty and angst (like the one we're enduring now).

A CAPS public service announcement
There's really not much I can say about this video from TMFHollywoodDan, except that every Fool -- nay, every investor -- should watch this very important PSA.

Sharing what you know
While many on Wall Street may treat investing as a zero-sum game, where there's a loser for every winner, that philosophy does not hold at The Motley Fool. One of the Fool's core philosophies is that, as a community, we can help each other become better investors. That certainly carries over to CAPS.

Already on CAPS, we're seeing numerous investors sharing their knowledge with the community. In some cases, it's specifically finance-related, but in others, it's specific industry knowledge. In a recent post on my own blog, I asked the CAPS community to show off their know-how.

Levitt is the first to go
CAPS' resident homebuilding commentator, floridabuilder, may have finished his 20-part series on evaluating homebuilders, but he hasn't stopped blogging. In this week's blog, he reviews the recent bankruptcy announcement from Levitt (NYSE:LEV) and reiterates some of the other public builders that he believes are at risk. Is Dominion Homes (NASDAQ:DHOM) next? Maybe Beazer (NYSE:BZH)?

And if that doesn't satisfy your itch for homebuilding talk, check out his thoughts on WCI Communities (NYSE:WCI).

New features
As one of the Fool's newer services, CAPS is definitely still in development. On any given day, I may log onto CAPS to discover a great new feature that makes the service more powerful and useful. In a recent blog, TMFKnave reviewed some of CAPS' latest additions.

Millions of Enrons
I know what you're thinking: Wasn't one enough? Spurred by an article about Morgan Stanley's (NYSE:MS) troubles, saunafool wonders whether the past few years might have spawned a whole bunch of Enrons.

CAPS or "real life?"
CAPS can be a great place to try out new ideas, tracking stocks that might otherwise not be appropriate for a real-money portfolio. How has that strategy worked out for CAPS-playing Fools? In his recent blog post, TMFBreakerDave asks whether players are having more success in CAPS or in real life.
