There are a dozen MarkDown implementations that are better than Grubber's piece of shit, and a couple that are actually nice. The lack of a decent implementation is not the issue. This issue is that Gruber is (regrettably but naturally) seen as the authority on MarkDown by a whole lot of people, and he's still encouraging them to use his insecure, bug-ridden disaster instead of pointing them in the direction of something that anybody outside of his use case would ever want to use.

He just needs to add a sentence or two to his website and he'll save countless developers a ton of headache. He just doesn't give a shit.

It's pathetic.
