YAPC Channel on Vimeo
I've created this YAPC Channel on Vimeo, currently it contains the (badly recorded) video files from our local YAPC::Tiny event, but if there are more videos about YAPC from all over the world that would like to go in there, I'd love to help. If you need moderator access to this channel (so that you can put your videos in there), please send me an mail.
ps. I found vimeo really generously provide 500mb upload per week, and they do not have time length limit per video, unlike youtube. It looks like it's a much better choice then youtube in my case.
