To keep this blog as readable as possible, I keep my techniques in a separate database using Freemind's mind mapping software.
Well They just upgraded and fixed a lot of the bugs that used to irk me. Notes no longer automatically pop up if you hover over a cell. The interface is cleaner overall and you can edit them using HTML. The preview pop up is pretty nice too. As far as keeping a technique journal is concerned, it's definitely the best solution I've run across.
