Which brings up, what happens if some credible expert votes for something, and five minutes later is told a better solution by someone who's completely new to the site, tests it, and finds out their solution is better? I've seen that happen numerous times.

The Stack Overflow solution has positive factors, but it also has negative ones, and some of them are eggregiously negative. There are a lot of high-vote solutions on there that are valid but far from optimum. Some because they were optimum at the time they were voted for, but no longer are, others for other reasons.
