I feel like playing with Tinderbox today

It makes me twitchy when I don't use Tinderbox for too long. It's one of the most interesting, powerful, and flexible apps I've ever known. It's a pointy-clicky graphical counterpart to Emacs. It may not be quite as tweakable as Emacs, but it makes up for it with ease of use.

And it makes a great blogging tool. You're soaking in it.
