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, 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 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.

It takes a lot of arrows to kill an elephant
As CAPS blogger TMFDeej points out, the auto industry currently offers precious few hiding places. Top-shelf players like Toyota (NYSE:TM) are struggling, as are those serving some of the fastest-growing markets, like Tata Motors. But General Motors (NYSE:GM) is an entirely different story. TMFDeej calls the old behemoth "one of the worst run companies that I have ever come in contact with." Click through to get more of his thoughts on the auto industry, and where you might be able to turn for quick profits from falling gas prices.

The best-kept secret of successful investing
What made Berkshire Hathaway's (NYSE:BRK-A) Warren Buffett such a great investor? There are probably at least as many answers as there are ways to leave your lover (50, according to Paul Simon). CAPS blogger Qovax has picked out his favorite of these reasons, and he thinks that it's something any investor can do -- if they're willing to put in the work. Curiosity piqued yet?

Blood on the streets
In the ongoing boxing match that is the stock market, CAPS member colonelnelson has been checking out a few stocks that have endured some head shots lately.

Head over to his blog for the breakdown.

July review
Though the market has been a tough customer lately, it has been kind to TMFHelical, who focuses on the areas of health care and biotech. In his recent blog post, TMFHelical reviews some of his moves in July, including why he ended his outperform on American Oriental Bioengineering and gave the red thumb to Genentech (NYSE:DNA).

Are investors overlooking Apple's cash earnings?
CAPS blogger turleymuller thinks that the expected 24% growth in Apple's (NASDAQ:AAPL) earnings per share doesn't do the company justice. He argues that the company is generating significantly more cash than it's reporting in earnings, making shares look even more attractive. Think he's right? Think he's crazy? Don't make up your mind without reading his extensive write-up.
