The Motley Fool's CAPS investing service is 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, the upcoming football season, 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, 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.

Commodity carnage
After a long bullish run for commodities like grains, oil, and metals, the market has hiccupped and taken commodity stocks with it. CAPS member StockPumper attributes at least some of the heavy selling of late to fund liquidations -- including the big Ospraie debacle. However, StockPumper is bullish on commodities when it comes to fertilizer companies like PotashCorp (NYSE:POT) and Mosaic. Head over to StockPumper's blog to find out why.

Reaching for the towel
In what seems to be a recurring theme, CAPS blogger sarcaz notes that he's sharing the pain of the big decline in commodities and energy stocks. Stocks like Trina Solar, Joy Global (NASDAQ:JOYG), and Atwood Oceanics have been taking a dive and taking sarcaz's score with them. But is there light at the end of the tunnel? Visit sarcaz's blog to find out what he thinks.

Awards ceremony: worst-in-breed homebuilders
All of the big boys have been gathered here by CAPS blogger floridabuilder -- KB Homes, Ryland, Hovnanian -- all present. The occasion? Floridabuilder is handing out awards for dubious distinctions like "worst land acquisition department" and "worst CEO." Click through to floridabuilder's blog to find out who the winners are.

MasterCard positioned for growth
If you listen to the pundits out there, you may end up convinced that there is trouble a-brewin' in just about every last industry. CAPS member LEGMAKER, however, thinks there is a great opportunity at MasterCard (NYSE:MA) as the global use of credit cards continues to grow. Head over to LEGMAKER's blog to check out his extensive reasoning for suggesting this stock.

Looking for bargains in energy/metals
Since the theme here has been somewhat tilted toward the fall in commodities, let's go ahead and turn to Imperial1964 and his search for a good stock in the energy and metals sectors. In his recent blog post, Imperial looked at a handful of stocks, including ConocoPhillips (NYSE:COP), Fording Canadian Coal Trust, and Titanium Metals (NYSE:TIE). Click through to his blog to find out which one he thinks is most promising.

AOB and why I like it
The title says it all! In his most recent blog post, CAPS member Killim1 takes a look at American Oriental Bioengineering (NYSE:AOB) and gives an extended pitch on why he thinks it’s a company to own. Hop on over to Killim's blog for the full scoop.

Google Chrome is not a browser
Say what? That's right, TMFMileHigh said that Google's (NASDAQ:GOOG) new Chrome browser is not a browser. So what is it, then? Come on, you know what I'm going to say -- click through to his blog already!

And 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?
