The Motley Fool's CAPS investing service is a great way for investors to work together to beat the market -- and maybe get famous while they're at it. Among its features, CAPS lets users blog about their picks, investing strategy, market view, their favorite ice cream flavor, or whatever floats their boat.

As the CAPS blogosphere continues to grow, players are adding more great content on a daily basis. To make it easier to find some of the gems out there, I've dug through the past week's posts to find some of CAPS' best insights. Of course, 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 heading over to CAPS and checking out what some of the other investors have to say.

Reading list
With the market and the economy in utter turmoil, what's this a perfect time to do? No, no, the answer isn’t “cry.” It's a perfect time to get your read on!

Luckily, CAPS blogger CMOCapital is in tune with this, drawing up with a reading list to keep you occupied while Mr. Market throws up all over our portfolios.

Sell your refiner stocks now
CAPS All-Star leohaas has been high on refiner stocks like Valero (NYSE:VLO) and Western Refining (NYSE:WNR). But no more. He has been watching the crack spread that refiners can earn and has decided that now is the time to pull the plug. Check out leohaas' blog for the details.

Fastenal: worth buying then, worth buying now
While nearly everyone else is focusing on the macro picture, CAPS All-Star weiwentg has been continuing to scout out opportunities among individual stocks. In his most recent post, weiwentg digs into Fastenal (NASDAQ:FAST) and concludes that this industrial-goods supplier is a good deal right now. Head over to weiwentg's blog to get his analysis.

A select list of stocks and my opinions about them
ikkyu2 is another CAPS member who’s still managing to look at stocks without losing his lunch, even as the market continues to gyrate. In his most recent blog, he has highlighted a number of stocks, including Apple (NASDAQ:AAPL) -- which he says he would "buy nearly any amount of" right now if he had money and didn't have to worry about diversification -- and Google (NASDAQ:GOOG), which he says is "getting to where I might buy them as a value play." Click through to ikkyu2's blog to see the rest of the stocks that he has his eye on.

BAC cuts dividend in half
Well, that tasty dividend yield that Bank of America (NYSE:BAC) was sporting for a while is no more. So what's a yield-chaser to do? Why not check out what TMFHighYield has to say -- he's running a CAPS portfolio focused on stocks with attractive yields. Click through to TMFHighYield's blog for his take.

If The Onion wrote Fool articles
As I've said so many times in the past, don't forget about humor! TMFBomb certainly hasn't. He's given us a handful of great headlines that The Onion might publish in its business section. Check out TMFBomb's blog to see what he thinks McDonald’s (NYSE:MCD) might do to the Big Mac.

And that's our round-up 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?
