I mean, youtube got rid of, or hid very, very well the ability to send users messages, and I can only find my inbox at all through a nest of links three deep. They have barbaric DMCA policies that allow for consequence free abuse and bullying, demonitize videos that discuss controversial topics, force a style of buffering that prevents people with slow internet from pre-buffering a video to watch it smoothly, and allow a sensational dying newspaper's mad ravings dictate who they work with or not, but yeah no, getting rid of annotations is just the worst.
Seriously though, Youtube seems like it's trying everything in it's power to be the worst possible service imaginable, and I can't help but think that it's their utter lack of real competition that is the source of their attitude. Sometimes it feels like most of the things they do are done for two reasons; one, *just* to test and see if people will still put up with it and if any competing sites do pop up as a threat to their monopoly, or two, to avoid doing any real work themselves.
