He meant it in terms of calling people stupid.

Two prolific projects that amount to far more than the vast majority of us of is will ever accomplish.

I suppose "prolific" does not necessary imply breadth or depth.

I believe an operating system typically implies both.

Prolific typically implies many things. I have a deep respect for linux and git, but neither are really prolific.

Anyway, I thought the OP meant he was prolific in his tirades, which is very true.

The way I interpreted the word was more "doing lots of things" and less "doing lots of a few things". Either is legitimate in retrospect.
