imgur should shoot big and host videos. Let people upload videos without an account, just like images. Fuck YouTube and its toxic comments. imgur's comment system and quality of comments are way better.
This still appears to be an unsolved issue (although, one could argue whether it is really an "issue"). Google's G+ approach (barring anonymous comments, etc) does not appear to have addressed the core concern.
Although I tried using imgur a few times, I could not upload images a number of times, subjectively I don't know how they get that much money for such service... bubble is it?
