With all the hub-bub around Screenr, I had to check it out. It is extremely easy to use. If you have not heard about it yet, Screenr gives you the ability to capture your computer screen, mouse movements and audio (e.g. software simulations). Once you click done, it compiles it and sends it and your text description out as a tweet.
While I was playing around with it, I realized I can capture my webcam on it...what an easy way to create a video post that I can tweet. Here is the result of a 2 minute investment of time.
If you would like to see it in my Twitter timeline, you will find me at http://twitter.com/minutebio (@minutebio).
