Maybe it's just my perception, but I think the Google and former Google employees I'm following on FriendFeed use the service much, much more than that of Twitter and Facebook employees (with the exception of FriendFeed employees, which themselves are mostly former Google employees). Not sure what that means though. I'd love to see some stats.
There was a lot of chatter about the future of FriendFeed this weekend. The short answer is that the team is working on a couple of longer-term projects that will help bring FriendFeedy goodness to the larger world. Transformation is not the end. Consider this the chrysalis stage -- if all goes well, a beautiful butterfly will emerge :)
The most damning thing is that no one from the FriendFeed team or Facebook has joined the community here that is talking about it to tell us what's happening in the future. That, more than anything I've written or said communicates the future of FriendFeed.
