I'm fascinated with the way that a bunch of old ideas floating around from the dot com era are back, and now succeeding. Many of these apps are explicitly social, and are benefitting from the larger user population and increased comfort - it took quite a while for Match.com to catch on, and sixdegrees had much of the Friendster model down by 1996 and flamed out anyway.
