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 college football team, or whatever floats their boat.

As the CAPS blogosphere continues to grow, players are adding more great content daily. 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.

Oil recovery will be awhile ...
Waiting for those shares of ExxonMobil (NYSE:XOM) or Transocean (NYSE:RIG) to come back? Well, hold your horses there, champ, because CAPS All-Star dwot thinks it could be awhile before oil prices come back around. Click through to her blog to see the numbers that she's throwing around.

Let's hope we're all wealthy and retired before this house of cards falters
Remember how Moody's (NYSE:MCO) and Standard & Poor's were partly blamed for the big debt mess that we're in right now? Well, according to TMFDeej -- and some very red-in-the-face S&P employees -- some of the debt raters may have known that they weren't exactly rating primo issues. Head over to TMFDeej's blog to see what I mean.

Great deal on NVIDIA, I hope
CAPS member DLai0001 is all over NVIDIA (NASDAQ:NVDA). Fortunately, there's more than hope when it comes to this graphics-card maker, and DLai0001 gives us one big, green reason why he likes this stock. Check out DLai0001's blog to read on.

Make the responsible choice -- close shop
Amid the turmoil in the financial markets, immense struggles continue at America's big three automakers -- Ford, GM (NYSE:GM), and Chrysler. What's there to do at this point? If you ask CAPS All-Star jhuangwithnmr, it's time for one of the big three to ride into the sunset. Hey, don't yell at me -- it was jhuang who said it, so head over to his blog if you want to argue.

Evergreen: The overlooked solar player
There are a lot of solar stocks out there. Some of them, like First Solar (NASDAQ:FSLR), seem to have popularity in spades. But have investors overlooked the much smaller Evergreen Solar (NASDAQ:ESLR)? CAPS blogger TheHuney thinks so. Click through to his blog to get the lowdown on Evergreen Solar.
