I was 21 when I joined in early 2OO4...and even then I was told I was, "too old." I wish I had learned about the site a little earlier; I think it would have been amazing to join the party in 'O3. From what I've heard, many of the first members were in their 2Os. Somewhere along the line, the main user age went down and the idea that this is a place for teens started. Darn kids need to get off my lawn already. cat_wink
I was involved with the original parenting guild when it was still alive and kicking, so I spent a lot of time surrounded by Gaians my age or older. Most of them seem to have left the site, but I still see a few floating around--including a certain gentleman who is in his mid-7Os now. I knew several Gaians who were on here with their older teen children or even grand children.
I've put so much into Gaia, and received so much back in the form of friends, that I'll hang around at least as long as they do. I'm always trying to branch out and make new connections, so who knows when I'll actually leave? yum_cupcake
