I use Tiddlywiki. It's end-user controlled, and works in any browser. I think it usually flies under the radar in these discussions, but it's really surprisingly powerful, I've found. It's the data and tools in a single HTML file, which makes it uniquely resistant to bitrot. There's a bit of a learning curve, though.
