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, yesterday's lunch, 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 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 the 110,000-member CAPS community and checking out what some of the other investors have to say.

Adrift in a DryShip
Dry-bulk shipper DryShips (NASDAQ:DRYS) turned a lot of heads in 2006 and 2007 when the stock ran up more than 1,000% in a little over a year. Throughout the stock's feverish spike, many investors stayed deeply skeptical about the company and its management. Today, the stock has moderated a bit from its highs, but its two-star rating on CAPS suggests that investors still don't think much of the stock.

This turkey is cooked
After mulling over what subjects he really knew about, CAPS player colonelnelson turned to political analysis. The country in focus was almost-EU member Turkey. While Turkey has been favored by many among the world's emerging economies, colonelnelson paints a picture that suggests more caution is needed about the country's economic outlook and, therefore, Turkish stocks like Turkcell (NYSE:TKC) and Turkish Investment Fund. Head on over to colonelnelson's blog for the analysis.

Monthly cost of Hummer 3 ownership
It's no secret that the Hummer division has not been kind to General Motors (NYSE:GM) lately. TMFPhila took a stab at why -- the outrageous cost of owning one of these metallic beasts. Hop over to his blog to see his back-of-the-envelope analysis on the cost of owning a Hummer.

My $300 billion solution
The government is busy trying to come up with solutions that will show voters that politicians are doing something about the struggling housing market and the perceived wrongs that have occurred over the past few years. CAPS blogger iamamartin thinks these plans are misguided and has come up with his own plan. Visit his blog for this mold-breaking idea.

The re-review of solar technology
Will solar power be the alternative energy source that ends up saving us all from escalating energy prices? Given the success of solar stocks, such as Suntech Power (NYSE:STP) and Yingli Green, that have entered the public markets over the past few years, it seems that many investors think so. CAPS blogger AnomaLee has tackled this budding industry in an extensive post that reviews the industry and the public players that you should know. Head over to AnomaLee's blog for the lowdown on solar.

SUN peeking through the clouds
CAPS All-Star TMFDeej thinks that there are too many unjustified clouds hanging around Sunoco (NYSE:SUN). Though crack spreads have plummeted as oil prices shot up, he cites a Credit Suisse report that contends that the pieces that make up Sunoco are worth far more than the company's current valuation. Check out his blog for the full story, plus some thoughts on Transocean (NYSE:RIG) and copper.

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?
