I think my point behind all of this is that we all make these mistakes. Likely every day. Most of the time we catch it ourselves. Some of the time the fix is pointed out by someone looking at it with fresh eyes. Once in a while we ship it to production.
If we can all agree that we're not looking stupid or dumb when this stuff happens, then we'll be more likely to ask for help, more likely to catch issues, less likely to spend minutes/hours/days on something and more likely to ship a quality product.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
