I was always surprised that a bunch of people looked at Facebook's website and said, yeah, I want their code to be the next big JS framework. Facebook has behaved for me for the past year or so, but for years prior to that, visiting their site was just an exercise in frustration for me. It was mainly because of components that remained in the gray loading state but never loaded. The messaging window used to do that for me about 50% of the time. Whenever I visited Facebook, I used to instinctively put my fingers over Ctrl-R in case I had to reload. Also, one time, they managed to deploy code that broke form submissions under Firefox but not Chrome. I would be more understanding if it dealt with some cutting-edge features of HTML, but these are HTML forms. Mosaic had support for them in 1993.
