The last time someone did this, they mistakenly used "0-5 BTC" as the lowest cutoff. You've made the same mistake. There should be "0-0.25", "0.25-0.5", "0.5-0.75", "0.75-1", "1-2", "2-3", "3-4", and "4-5". Extra poll options are better because now we've lost valuable information at the low end. In 20 minutes, 65 people say they own 0-5 BTC. That's anywhere from $0 to $1385. That's a massive range. We now have no idea how many "casual" bitcoiners there are, because casuals will only have like $200 max.
EDIT: Here's what your poll looks like as of t=35min:

Leftmost bar is 0-5BTC. Rightmost bar is 100+BTC. Oh look, now we know basically nothing about the two most interesting ranges.
EDIT2: As of t=44min: http://www.wolframalpha.com/input/?i=bar+chart+154+21+26+15+... ... Pretty hilarious.
