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.

TMFDeej calls the old behemoth "one of the worst run companies that I have ever come in contact with."

Are investors overlooking Apple's cash earnings?

Don't make up your mind without reading his extensive write-up.
