We’ve seen lots of services that allow us to share photos and music at Twitter but we have yet to see a service that will allow us to share videos. Not quite, because here comes Youtube Tweeter, a service that allows you to post Youtube videos in Twitter. It is very easy to use, all you have to do is put in your username and a YouTube link. Youtube Tweeter will then generate a link and a button to post it on Twitter. Every time someone clicks that link in your tweet the Youtube video will pop up and the video will play.
