"Bragging" seems unnecessarily pejorative. Reading the information about his patents didn't sway me one way or the other the first time I visited his site, but I can see it being relevant data for some of his audience. The (superior) content of his books did sway me, as did Mark's willingness to make many of them available for free. I've since had occasion to interact personally with Mark, and I've unfailingly found him to be gracious and personable; "braggart" does not apply, in my experience.
It's just a basic resume credentials, the same as job experience.
There is another HN thread talking having personal projects online.
