He also horribly fails at updating. His whole plan seems to be writing emacs tutorials and selling them for money. (I didn't read the whole website, maybe there are more plans, most likely not better.) Besides being an obviously bad business model, he is actually very bad at writing; which means he can't even show his tutorials to a potential employer and expect to get a technical writing job or something like that.

The comments in the lengthy HN discussion suggest that his tutorials & other documentation are well-written, it's just his personal stuff which is written in his horrible idiosyncratic style.
