Friendfeed, for me, was the only social network that became truly social, where I felt like people connected with others. That's as much a function of the people here than anything else. The community is the biggest loss.
Looking (and taking screenshots) of some of the threads that were important to me. Among those are the comfort when my dad passed last fall, but also the joy that here has seen. The weddings, the babies, the people helping people, all of it. :) - ellbeecee
