I've been on friendfeed for almost a year now and have been fairly active on it.
For those on Twitter and other media sites, here's what you are missing.

The conversations that you have on friendfeed just aren't possible with Twitter. Twitter is ok if you just want to talk about what you are doing, but beyond that it's pretty much useless.
friendfeed is about having conversations with as many people as possible.
Anyhow, the thread I linked to is just one example of why I like it better than sliced bread.
