Maybe some people do, personally I'm more familiar with the works of Fabrice Bellard, and that's probably fair enough since I expect I have more pieces of software derived from Bellard projects installed on my machine than I do software derived from Jeff Dean projects (not to criticise Jeff Dean, who I'm sure is very inspirational).

I just wanted to do a +1 here, but as it is not very HN-worthy, I'll provide a little bit more of work, and just say that a search in HNSearch for "Fabrice Bellard" produced 3 pages of results for tha last year, whereas "Jeff Dean" only produced 2.

Personally, I feel I've been more exposed to Fabrice Bellard's work, which might be not true, but I first learned of Jeff Dean's existence yesterday.
