> Friendster was the first social network
Friendster was not the first social network.
sixdegrees.com had it beat by 5 years.
AOL has them beat by another 5. You need to go back to ARPA to find the first one. Social networks are just networks with humans at each end.
Also LiveJournal, launched in 1999.
It all depends on how you define "social network". We had BBS and forums that operated much like "social networks" in the mid 90s. I don't think being "the first social network" is particularly interesting or noteworthy.
