I agree with all your points, but for everything that vimeo doesn't have, youtube does. (content wise)
what kind of chaps my ass though is the viral video thing. remember the video of the german (?) guy jumping into the frozen pool? I saw the OG upload of it with only a couple thousand views, then I went to find it again the next day and PAGES of the exact same video had been uploaded by dozens of random users.
If I was that guy I would be pretty mad about so many people trying to take credit/make money off of my video.
not to mention that 90% of viral videos are fucking stupid as hell anyways. oh look a panda sneezing, better watch it 50 times then post a hundred comments about how cute it is then share it on facebook!
kinda rambling cause im a tad stoney baloney but in a nutshell, I hate youtube and the youtube community, but if it disappeared all of a sudden, I would miss it greatly.
