Actually I was never active in Second Life. I joined few months ago, created avatar, started to explore, to investigate, participated/ audit few lectures and that was all. I never had any intentions to go deeper: sell, buy, use entertainment facilities, or interacting per se with unknown people. I was usually invited to events (education content).
Second Life, beside server, metrics and other bugs, have many other failures I described here. It is column in Serbian though, for those who speak Serbian – it is realistic and full critique on SL with some stats. It is very easy to quit something that doesn’t have the future. With simply: uninstall!
