This is not good news. One assumes that, if Allan Odgaard could make something approximating a living by improving Textmate, that’s what he’d be doing, just as he’s done for the last eight years.
Though I own a copy, I don’t use Textmate a lot. I’m a BBEdit guy, and the XCode editor is fine with me, but lots of programmers love it. Textmate’s plug-in “bundles” were truly pioneering, and they’ve had a lot of influence.
