This is the same guy who hacked GitHub (and Rails) with the multiple assignment hack, among other things.
On HN? Or somewhere else (if so where?) where he is "as famous as PG on HN".
If you mean he is as famous on HN as PG is on HN I don't think that is the case.
* How famous PG is in HN
* How famous homakov is in HN
HN has become mainstream enough that a lot of readers don't know who pg is. This is what getting linked from reddit, digg, etc leads to. I don't mean this is bad, or good. It's the way it is.
