I maintain several different wiki. They each have their own RSS feeds that can be subscribed to.
I maintain these wiki’s mainly as a way to track my learning, tips, and tricks for specific subjects. I started them long before this site, and had I made this site first, I may have incorporated them into it. But there’s a lot of knowledge in them, so for the time being they’ll stay separate. Here is a list:
The wikis are “Tiddlywiki’s”: http://www.tiddlywiki.com/
They can be hosted for free over at tiddlyspot.com
I think they’re a great way to quickly get data online.
