My group of real-world friends did an overnight migration (well not quite but once it started it was very fast) from Livejournal to Facebook; in retrospect that was a mistake and we all should have stayed on LJ. The killer feature? Being able to tag people in photos, such an obvious thing, but LJ was unable to do it. Add events and it was game over for LJ. Incidentally, I said at the time, it was a massive strategic blunder for Google+ to launch without full integration with the Google Calendar. People want a one-stop shop and FB was it for photos and events.
