Posting a question on SO and having it answered is interacting with people. I'm unsure how you could interpret that any other way. And given that podcasts and YouTube were part of the answers, I think it's clear that passively listening to people counts as an interaction as well within the context of the question.

The Python question I'd say is more narrow, as it asks specifically about "new tools and technologies". What if I have a question about an tool I've been using for a while?

In any case, my point is not what market share Clojure actually has, but that there's reasonable doubt in using SO's developer survey as a basis for that answer. If a far smaller percentage of the Clojure community uses SO than is average for a language, then it's going to skew the results.
