There are many who watch hundreds of YouTube videos in a day and many share those videos with their friends via twitter, Facebook and other social networking sites. But many don't know about the cool feature which you have in Gmail. The cool feature is that you can share YouTube videos with your friend via Gmail, so that they can watch YouTube videos in Gmail without leaving the page. One way is send the link of the video in Gmail chat so that they can watch it on small screen within the chat window as in the image below. And another way is to send the link of the video as mail and that works only if the recipient is reading the mail in Gmail. However sadly, the videos cannot be played back in Gtalk at the moment. Lets hope that Google may launch this option soon.
