TiddlyWiki can save!

A completely browser-based client side wiki is cool enough, but the recent versions of TiddlyWiki can even save your changes! That only works in Firefox and IE right now (I’m using Safari at the moment), but that is quite the achievement. Even the upgrade process is impressively easy.

For folks into Getting Things Done, Nathan Bowers has put together GTD TiddlyWiki, a repackaging of TiddlyWiki that is designed to keep all of your next actions together.
