That someone can post this on HN and get a bunch of invites back.
Does doing something like this scale? What if everybody just decided to post "hey I'm coming to SF is there a place for me to crash" or "hey I'm coming to NYC anyone want to have coffee?" or "I have a problem writing perl..."
Since there are companies that you are trying to reach, and you must have some idea of the type of company you want to reach, why not put some effort into doing something other than the obvious easiest thing which is to post an "Ask HN" and see who bites?
(For the record I wouldn't feel the same way if a top commenter who spends much time on HN made a similar request because at least they have put time and effort into HN (and I don't consider my karma as anywhere near that point for the record.)
