Vitamin's Ryan Carson just wrote a piece about why he doesn't use Social Software. He basically says he's too busy.
Facebook is the only on-line service that has it right at such a complicated level. They have a nice group of services (blog, photo, notes, calendar, groups, friends) and a decent one stop interface to follow along.
The secret is that all the services write a "story" which is aggregated into a continious story of your on-line life.
I'll have to see how well integrated they are with Google Personalized Home Page and MyYahoo.
SpiralFrog plans on giving away a huge amount of music for free. It will be in Windows Media Format and uses MS DRM to protect the music. You will have to contact their web site periodically to make sure the music works and you won't be able to share it. As a result, nobody will use it.
