Here is an alternate proposal that leaves no one at the top level right now so the ladder will be reasonable for a while to come. It shoots for about 40% more XP gain required at each step (the second-to-last column).
I'd set the votes at 2 per level, 0..42. 2 extra votes per level is plenty little reward. I think going lower than that is more likely to end up with people being so conservative about casting a vote that you'll get lots of nodes with no votes. That will mean no reward for simple, run-of-the-mill contributions.
"Inflation" of the rep of good nodes will not be reduced by reducing the number of votes. So reducing the number of votes will mean that the top-rep nodes will keep inflating as the number of users increase and the ordinary nodes will get less, widening the gap and increasing the motivation for XP whoring.
Update: This may have the wrong number of levels. The problem with listing the borders between items in the same line with the items is that it isn't clear if you are listing the upper border or lower border. I didn't think Petruchio was proposing "level vroom" be renamed (yes, I only skimmed the text). We could name "level vroom" as "gods" which would solve the problem of the hard-coded 11s in the code and make for a fun message for top-level members.
