Not sure about 2006 but 2008 when I joined was really busy on here. There was a lot more discussions/chat threads/games etc (we were still on the old server and PM’s were called U2U’s iirc).
There was also a lot more drama though, some of it funny but some of it spiteful. But it was also a lot more fun on here. Everyone was younger so I guess also had more free time. I do miss old TiBB sometimes and all the members from 2008 who no longer frequent here.
