For me, SL is a place to go to relax and/or get creative, without having to be social. My work requires me to be social and when I get to have SL playtime, that is me time. I do get social with my small circle of awesome friends I have made in SL over the years, but we are usually voicing on Discord while we play in SL. Why? Discord rocks, and I always have technical problems with getting SL voice to play nice with my headsets. It's just super frustrating, so why. There may be a lot of folks who come here to be social, but there are also a lot of folks who come here to escape being social. I'd much rather explore interesting sim builds solo or with a friend I'm talking to in Discord than go to a club build. Also I suspect a lot of folks who come to SL are introverts, otherwise they would be getting their social on in RL. If I am being social, I like nice people.
