If it's intellectually gratifying, why should it be anonymous? There are very few things that I can think of where that would make sense, and most of them would be research into 'politically correct' territory; i.e. definitely not hacker stuff.

Interesting idea, but it just doesn't work for me...

it could just be something different. i know of engineers who can't fathom the idea of pitching their idea to an investor, let alone writing something that might be a great read but they don't want it to be associated with their name on a google search for whatever reason.
