If you already have a specific aim for a ratio of you talking to the subject talking, why do you take feedback?

Interesting. You're right in that it's not an interview -- my terminology was misleading.

I'd rather hear more from the creator of Gensim. Has John D. Cook built anything impressive?

Umm.. I have nothing against gensim or the author, but aren't you assuming that JDC hasn't. He has been working in consulting and probably under a lot of NDA contract clauses and has not been able to publish? I don't know his work, just like his blog.

well his blog, which he has continuously published on for (at least) the last five years, is certainly impressive.

His posts are practical-minded but also evidence a deep knowledge of the subject matter. The ones on applied probability theory, for instance, are of very high quality.

(i don't know John personally, nor any affiliation with him)
