I am not sure what your purpose with this poll, but I don't think the results are indicative of anything. It depends what stage they are in. We are a startup, bootstrapping with our own money, and went private beta about 2 weeks back, so we are on one VPS, where db, 2 RoR apps, transcoding, blog, mail, queueing server, storage, everything on it. Its far from real scenario, where (hopefully) some day we'll be serving thousands, if not millions, of users.
