Yes, it's excellent. I've been using TiddlyWiki for over a year now and (gradually) moving all my notes from Evernote, OneNote and other note-taking/storage apps I've used. I mainly use it through an app called Quine in iOS and TiddlyDesktop on Mac. There's something about Tiddlywiki that makes it a delight to use. It's also supported by a great Google Group.
