YouTube is very much like flickr,
but for videos.

You can upload videos in a number of different formats
( .AVI, .MOV, and .MPG ). Videos can be of any length, but must be less
than 100 mb in total size. Editorial restrictions consist of no “nudity
and your video must be appropriate for all audiences.”

The
service is completely free to users (publishers and viewers). YouTube
converts video to a flash format, and therefore upload and playback is
extremely fast. In our tests, videos uploaded significantly faster than
in other services.

YouTube is also a sharing network. You can add friends who are also
member of the network, and email any video to anyone. YouTube also
provides easy to use copy/paste code for emailing and posting on a
website. You can also tag your videos, which results in bunching in a
very similar way as flickr. Overall, the service is excellent.

The service has recently been launched but seems to have quite a few
users who have posted lots of content. Our absolute favorite is Matt Dances around the World.
It shows an ex-programmer who’s travelling the world and dancing at
famous locations – it’s awesome and very popular on the site. Other
favorites are this and this (that’s me in the red shirt. ok, not) (how do people do this?).

I suspect YouTube will be quickly acquired and/or duplicated. We love it.
