I'm actually a little surprised how evenly spread the votes are. From this data, meager though it is, there's at least the suggestion that many groups actually do start out with a first-time DM (since option 1 is the most common, but the other two combined, both of which have a first-time DM, are 55.9%.) Meager data, forum poll, early days, etc. etc., I know not to make much of these results. Just surprising, since I expected something a lot closer to like...80% "player with an experienced DM."
(To explain a bit further: in order for us to get to 80% "player with an experienced DM," assuming no one changes their vote, we would need to rack up 61 more votes for that option without even one person voting for the other two. Even getting 30 votes all going to that one option would be pretty dramatic at this point, so these results are significantly different from what I expected.)
