The Motley Fool's CAPS investing service is another great way for investors to work together to beat the market. Among other features, CAPS lets users blog about their picks, investing strategy, market view, favorite rugby team, or whatever floats their boat.

As CAPS blogging catches on, players add more great content on a daily basis. I've dug through the past week's posts to find some of CAPS' best insights. 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 checking out some more.

Pick of the month: NVIDIA
Continuing his free CAPS stock-picking newsletter, EldrehadsPicks -- the alter ego for CAPS All-Star TMFEldrehad -- made NVIDIA (Nasdaq: NVDA) his April pick. Although Eldrehad admits he usually looks for stocks that are off the beaten path, he has been impressed by this company's growth story. He concluded that "one can't help but think that NVIDIA will be a powerful force in the computer graphics arena for many years to come." Read his post for a very detailed write-up of the opportunity this chip maker presents.

Waiting on Starbucks
CAPS All-Star iamamartin thinks there's a lot to like about coffee king Starbucks (Nasdaq: SBUX), despite its recent tribulations. However, he's sitting tight for now and watching the stock's price continue to fall, in hopes that it gets to just the right point. Check out his blog post to find out exactly where he becomes a buyer.

Hansen's crisis
Although rknapton assures readers that there's no crisis going on at Hansen Natural (Nasdaq: HANS), he notes that the Chinese word for "crisis" is comprised of the characters for "danger" and "opportunity." Click through to his blog to find out where he sees the danger and the opportunity in Hansen's current situation.

Intrepid Potash
The largest U.S. producer of muriate of potash, Intrepid Potash (NYSE: IPI) recently raised nearly $1 billion in its IPO, obviously taking advantage of the ongoing agricultural boom. CAPS blogger cuin103 wonders whether Intrepid's worth a shot, or whether "ag" is all played out. Click over to his blog to join the discussion.

The black gold review
CAPS blogger AnomaLee isn't so sure where the prices for crude oil are headed, but natural gas is another matter. This CAPS All-Star thinks the high prices for natural gas are here to stay, and predicts that companies like XTO Energy and Chesapeake Energy (NYSE: CHK) will benefit most. Click through to AnomaLee's blog for the full review.

Buffett writing index puts
Think Warren Buffett only works with plain-vanilla securities at Berkshire Hathaway (NYSE: BRK-A)? Think again. Doing a little sleuthing in Berkshire's 10-K, GS751 found a section disclosing $35 billion in index puts. In plain English? Buffett is still very bullish on the market's long-term outlook. Check out GS751's blog for the full story.

Positively Pepsi
JDSancho kicked off his brand-new blog by giving his take on food and beverage giant PepsiCo (NYSE: PEP). He thinks that the stock is at an attractive price right now, based on Pepsi's great brand and the potential for increased global exposure. Peruse his blog for the full scoop.

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?
