Many great things suck. PHP will still be the most accessible backend language for a long time and only JavaScript stands a chance at outcompeting it for a long time. (And yes I know JavaScript is normally seen as a frontend language)
PHP, Javascript, C, C++, Java. Arguably "great" languages given their success, and each attracts a mob with pitchforks and torches wanting to burn it down.
I would like to see Hack take off a bit more though. The XHP extension alone solves so many headaches with templating. Treating XML elements like first class citizens and having the language be able to reason about its current context, and not having to echo HTML strings everywhere and just hope you escaped everything properly, is something I wish PHP had picked up years ago.
