My intention wasn't to attack academics. I was just trying to point out that being wrong is something that happens all the time, especially when something is in-progress (pre-print). How many papers written by people are withdrawn during peer-review, or while in the preprint state?

If someone had a blog about their research on a math problem, and they figure out one day that what they wrote a week before was wrong (retracting it), would that be a bad thing? I don't think it would be bad, but that's not how academics approach things.
