The Motley Fool's CAPS investing service is a great way for investors to work together to beat the market. One feature in CAPS allows users to set up blogs to talk about their picks, investing strategies, market views, or their favorite ice cream flavor -- whatever floats their boats.

As CAPS blogging has caught on, a lot of great content goes up every day. I've dug through all the blog posts over the past week to bring you some of the best posts coming out of CAPS. There's no way I could hit all of the great stuff in the CAPS blogosphere, so when you're done here, I highly recommend checking out some more.

Final post in the housing blog series
Alas, the day has come. CAPS All-Star floridabuilder has penned No. 20 of 20 in his series on housing. And the weekly series he started has hit a speed bump as the misery in the housing market created more business for him. He has promised to continue posting sporadically, a promise CAPS players hope he keeps.

But hold on! Before I get too wistful, let's tackle the issue at hand -- his final post. It's a good one, and with the usual wit and insight he covers why some homebuilders like WCI Communities (NYSE:WCI) and Levitt will likely stay in the dumpster, while others like Toll Brothers (NYSE:TOL) and KB Home (NYSE:KBH) could be good long-term investments.

And for a little extra floridabuilder flavor, check out the interview that TMFHollywoodDan did with him.

But the light is so much better over here!
There's not much more that I can say to chk999's blog post than "Bravo!" It hits a big issue right square on the head. It's short and sweet, and I'd do a disservice by summarizing it here. So go ahead, you're not doing work right now anyway -- click through and read it.

Dissecting a scary stock
Investors in a stock are likely to get riled up when you call their stock the "World's Scariest." This is exactly what fellow Fool Rich Smith did for DryShips (NASDAQ:DRYS) -- and it sure ruffled a few feathers.

CAPS All-Star TMFEldrehad was one CAPS player Rich quoted as a DryShips bear in the piece, and Eldrehad took the battle to his blog. He dug in a little further into why DryShips' profits and performance may belie the risk in the stock.

The mosaic theory of investing
In a recent post, CAPS All-Star luvb2b defines the mosaic theory as "collecting public, non-public and non-material information about a company in order to determine the underlying value of the company's securities and to enable the analyst to make recommendations to clients based on that information" (luvb2b credits Investopedia for the definition).

Taking theory to practice, luvb2b applied mosaic theory to Ascent Solar, a small thin-film solar company that is partly owned by Norsk Hydro (NYSE:NHY). Luv's conclusion? You know you're going to have to click to get that, don't you?

The worst stock in the world
CAPSTV delivers again! In this most recent episode from TMFHollywoodDan and The Motley Fool Community Players, a woman who must be related to The Duke of Wall Street sternly advises against falling for the siren song from Telkonet. Worst stock in the world? Weigh in!

The China disconnection
With PetroChina (NYSE:PTR) and China Mobile (NYSE:CHL) both worth $400 billion or more, and a number of others not far behind, it's tough and getting tougher to ignore China. And everyone loves China, right? I can't tell you how many times I've seen the CNBC commercial where they make it seem Warren Buffett is saying you're crazy if you don't invest in China.

But still, some investors, like kristm, aren't quite convinced that China is a you-gotta-have-this situation. He cites a number of reasons, and his post is followed by some good rebuttals.

A stock market Halloween
I may be a day late and a dollar short bringing up this post, but rvanzo's ideas are funny. Bonus points to anyone who spotted any of these costumes in your neighborhood last night.
