So far it's cleaner than FB and MSpace; more refined. I am beta-testing this out for a company I work for...so far they love the possibility of not even having to open up multiple applications for working with documents (aka The Cloud)...Although their API for trying to get a HQ Cisco-like Telepresence video-conferencing is going to be lacking. IT guys are strongly thinking of converting over almost immediately after the full-release goes live.
