Took the survey.

Would probably not have defected a year ago, and it would not have been an easy decision for me at that time.

I appear to be getting better at estimating.

I think the IQ questions should probably just be dropped from future tests. A number of people get tested as kids and get crazy numbers and never get tested again (since there's no real point, and people are generally afraid of seeing that number dive, people who get a crazy number are probably less likely to retest than others). That's a charitable explanation for the results in last year's survey, which I didn't take.
