Let me provide a data point: to the best of my recollection I have never been asked to solve a captcha on math.SE or meta.math.SE. This despite the fact that I am a fairly regular user and I do sometimes edit posts several times in rapid succession. (On MO, where I think I must be one of the most active users, I have been asked to solve perhaps 10 captchas in the last year and none in several months.)

I say this not to undercut those who have experienced unpleasantly many captchas. On the contrary, it looks to me like there may be some problem with the captcha algorithms. To tell someone to look forward to 2/3 reduction of captchas with 10K reputation when other users are not experiencing any captchas at all doesn't seem fair. Or perhaps it is, but it's hard to know, since the entire captcha system seems to suffer from a lack of transparency.

If there is a cogent explanation for why this feature is needed at all, I would like to read it. Perhaps it would be worth trying out a temporary moratorium on captchas? Then we could see to what extent they are actually necessary and beneficial.

Update: I just got my first CAPTCHA on the site. I saw a question which had a maximally nondescriptive title ("How to solve this one?" or something close to that) and decided to edit the title to something more reasonable. My first chosen title spilled over onto a second line, which I decided was unnecessary, so I edited it again to shorten the title a bit, and then got a CAPTCHA. Only two edits altogether.
