It's no secret that I've been a fan of Friendfeed from just about the beginning.
Watching the service mature, change, experiment and react to suggestions by users has been not only fascinating ..... but I've always felt just a preview of the 'next big thing'.
While I'm the first to admit I've never taken the time to truly leverage Friendfeed's capabilities like Robert Scoble, Louis Gray and others have (particularly lists), those of us that have watched Friendfeed evolve and participated as possible, easily saw the potential of what these ex-Googlers were doing.
The one thing Friendfeed still lacks is a guide of sorts for new users. The feature set is not yet obvious despite numerous changes. (I have been asked by lots of people why I'm so loyal to Friendfeed. The reason they ask is that if you just stumble across it, you can engage, learn, even have some fun .... but you won't really realize what it can do).
Factually, in the past year, some of my best (and profitable) business contacts have been made on Friendfeed.
