Mozilla are looking for a Quantitative user researcher which sounds cool. The emphasis on user research sounds right up my street, particularly the need for mastery of experimental design and statistical analysis. It kind of takes me back to my PhD and work on SalStat (still going strong).

The problem is my covering letter. Can anyone here tell me what style of covering letters are preferred? Long and detailed explaining why I meet each of the requirements? The standard 3 paragraph ["intro", "I'm cool", "thanks"]? Or some combination in between?

In the meantime, I've released Roistr which does some basic semantic analysis / text analytics stuff. I put up some demos but it's hard to really show how useful this thing is. It's based on the open source Gensim toolkit along with numpy and scipy.

Scipy sounds like it's going places. Travis Oliphant recently announced an initiative to bring it to big data properly. I have an idea of what he means and it would be very cool.
