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 keep adding great content every day. And that's why I've dug through the past week's posts to find some of CAPS' best recent insights. With room for only six 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 that you check out some more.
