Web 2.0 Question:

Video Sharing is a similar tool for sharing videos, with some sites specialised in specific types of video. One of the most popular is youtube http://www.youtube.com. A site dedicated to teachers for educational use is teachertube http://www.teachertube.com. Video sharing sites are usually searchable, and allow users to post, comment on, tag and watch videos. A number of communities exist for producing and sharing videos around a common interest. More recently, sites have appeared which allow users to edit their video clips online and add sound, subtitles and so on.
