The Motley Fool's CAPS community 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 enables members to blog about their picks, investing strategy, market view, yesterday's lunch ... or whatever else floats their boat.

As the CAPS blogosphere continues to grow, members 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.

Buffett and Gates tour Alberta oil sands
One of the things that I find most amazing about Berkshire Hathaway's (NYSE:BRK-A) Warren Buffett is that he's always doing his own thing as opposed to following the crowd. That's why it's interesting that -- as TMFDeej points out in his blog -- Buffett and Microsoft (NASDAQ:MSFT) founder Bill Gates were seen talking with companies involved in the oil sands in Canada. Hop over to TMFDeej's blog for the full rundown of the trip.

Attention Facebook and MySpace Fools
Do you find it difficult to balance the time you spend between your Facebook profile and your CAPS portfolio? Well fear not because TMFJake is coming to the rescue. On his blog Jake tells us all about the new CAPS widgets for both Facebook and MySpace so that you can find out what your friends and stocks are up to all at once. Check out TMFJake's blog for the details.

Wind is blowing in
Is it time to take wind seriously? CAPS blogger parker3773 thinks so. He suggests checking out funds like First Trust Global Wind Energy and companies like Owens Corning, which makes materials that are perfect for wind turbines.

Why you should take a look at gasoline
While we're on the subject of energy, let's head over to the blog of blade5adj. blade took a look at the EIA report on crude oil and gasoline inventories and highlighted the fact that gasoline inventories have now fallen for four straight weeks. He concluded that it may be time to forget crude and start thinking about plays that emphasize gasoline prices. Rather than suggesting a major like ExxonMobil (NYSE:XOM) or a gasoline refiner like Valero (NYSE:VLO), blade recommended looking at the United States Gasoline Fund, which looks to track gasoline prices directly. To get blade's full color on the situation, head over to his blog.

Waste Management
The business may be all about garbage, but the company is anything but. CAPS blogger RonChapmanJr highlights a quick overview of Waste Management (NYSE:WMI) and kicks off a discussion of the stock's prospects. Head over to Ron's blog to join the fun.

The SEC is putting EDGAR out to pasture
Admittedly I'll be sad when trusty old EDGAR -- the SEC's repository for company filings -- is put out of commission. EDGAR and I have shared many a long hour digging through a 10-K or picking apart a proxy statement. But even the government eventually catches up with the times and based on what Tastylunch has to say, it sounds like IDEA will be a big step forward. Click through to Tastylunch's blog to read about the upcoming transformation of the SEC online.

What I've learned
CAPS member Imperial1964 is wrapping up his first year of investing in stocks, and boy has it been a crazy one to start on! In his post he shares some of the lessons he's learned through real-life investing as well as using CAPS. He also details why his pick of Unit Corp (NYSE:UNT) was dazzling for him while Portfolio Recovery Associates (NASDAQ:PRAA) fell flat. Get Imperial's full story by heading to his blog.

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?
