Vimeo is slow to use, and it doesn't offer HD by default unless you pay. It's far behind Youtube where you can upload 10 hour videos, and double HD. Not that I see the reason why, but my point is that we passed the year 2000 about fourteen years ago.
The most annoying thing with Vimeo, is hat you have to wait in that made up line after you uploaded a video. There is no line, and I am not going to pay for something as slow and backwards as Vimeo when Youtube does it better for free.
