I did some analysis a few months ago and collected the names of approximately 100,000 buckets in the wild. Rough numbers, about 5% are open to the public for anonymous read, and about 5% of those are open for anonymous write.
I'm convinced that Chris Vickery, the guy behind a good many of the open bucket finds this year, has access to enterprise firewall/proxy logs. Not because the buckets would have been hard to find, but because you could spend a lifetime looking through thousands upon thousands of open buckets before you find anything interesting.
