Right now this list isn't very good. Most of the people on it aren't researchers  Walter Bright? Yukihiro Matsumoto?
Guido van Rossum? Brendan Eich? Making a popular language doesn't make you a PL researcher. 

I'd be willing to make this a real list of PL researchers, but before I waste the time, I'd like to know if anyone else thinks it is a good idea to even have this article. Most of our articles covering PL researchers are (roughly) stubs.
