I am looking for the best video uploading site that rivals Viddler.com. Just so you know viddler is 500mb limit, batch uploading of videos and it has a in-video tagging so you can tag specific events within the video and only watch that part rather than the whole video.
As far as I know YouTube has a 100mb & 10 min limit for "normal" registered users, so that wouldn't be better than Viddler.
Vimeo is great - here's one of my clips. Nice clean site, with plenty of upload quota (not sure of the exact amount).
