Second Life - a world in decline?
General Discussion
I'm very optimistic about the future of SL, especially since the announcement of the new CEO. I think that it's a very good thing to have someone steering the ship that knows about managing IT shops as well as gaming and virtual worlds. It's a much better fit than having someone with a marketing background in that position.
From what I can gather, SL isn't in decline but has plateaued which is just fine with me. It's gone through the "bright, shiny & new" phase and now is progressing to "stable & established". I have to laugh when I read about the "good old days" which supposedly ended in 2007 especially since I didn't join SL until 2008.
We've been able to create and maintain our own little historical community for quite a while now and I think it just keeps getting better thanks to everyone that contributes on a continual basis.
All and all life in SL is good
