I think the ambiguity is kinda resolved by the fact that the previous question was about comments and this one would be largely redundant if interprete as also about comments. Also, the timescales in the question make better sense in reference to actual posts.
I agree it would be better if a bit more explicit, though.
The question “How Long Since You Last Posted On LessWrong?” is ambiguous—I don’t know if posting includes comments or just top-level posts.
I assumed it was about comments, because only a handful of people would have posted a top-level post to LW ‘today.’

I assumed it was about posts, because of the wording—it said “posted” not “commented”!
