I know I'm working on something, which is something I swore I would never, ever do again.
I'm even almost figuring out minor bits of code to make things work, for which I owe @Thenomain a big thanks, due to the stuff he's assembled that makes it easier to learn by observing simply how things are working, and answering questions when there are any.
Wiki-fu prettiness for character pages is one thing. Wiki-fu setup and customization... whole different animal. @Bobotron offered invaluable help there, too.
Between those two things alone, I've learned one hell of a lot -- and while the project may never be more than a pile of practice and puttering, that never ever has eroded considerably. That's really sorta... huge, even if it doesn't sound like much.
In part, I think this forum helped kick off the real sea change. The open exchange of information is, in itself, huge. While web sites have been around for ages with info on them, the interactivity factor for Q&A alone makes a world of difference.
