I played WoW for 5 years, on and off, socially to start with a single friend, then joined guilds. It definitely is one of the best parts of the experience IMO - I'm like you, I hate socialising in real life, but in an MMO I'll gladly help people out or chat for hours. The built-in voice stuff in WoW is shit, though; everyone either uses Skype or dedicated MMO apps like Teamspeak or Mumble.
Also, Buddy Bradley - did we become contacts? If not, I'm catabuca.
