Employees in the office used to ponder this question about corporate technology not easily available to consumers.

Today the question, usually asked from home or a cafe, is: "Why can't I do this at work?"

Innovative, user-friendly offerings -- Skype, Facebook, Twitter, mash-ups, YouTube, wikis, and the like -- take root and thrive as consumer offerings.

Corporate IT departments meanwhile often seem oblivious to their potential usefulness, even as workers wonder at their absence. But increasingly such technologies are being used for business.
