Have you used Meerkat?
If you have an iPhone or iPad, check it out now. This new livestreaming video app has been one of the hottest new apps since it was released earlier this year. What the app lets you do is post live streaming video from your phone in a very quick and easy way, and to watch livestreams from your friends.
Meerkat ties in with Twitter, so whenever you start broadcasting something, a link automatically goes out to your Twitter followers notifying them of the live broadcast.
