Everyone seems to be text messaging. When you're working at a computer though, it can be a pain to keep picking up your phone to reply to a text. If you have a Google account, you can send text messages from your Gmail inbox and get the benefit of using a larger keyboard.
With "My Queue" you can quickly save videos to watch later.
To add an item to your queue just click the sign next to the video.
Once you've added a video visit "My Queue" to start watching!
