I recently came across a Twitter post from @simbeckhampson which brought me to this Youtube video. It is a video of Paul Simbeck-Hampson in Bavaria demonstrating Amplify which is an autopost tool that automatically posts something you've written in one social media to another, or several others. For example, you can post something on Amplify and have it simultaneously (well nearly) posted to Facebook, Twitter and other networks.
But the really cool thing about this demo is how many social media tools are being used here at once. Paul is demonstrating the power of Amplify connectivity in Second Life by showing how a post made there can get across to multiple networks with one hit. He shows us his Twitter feed and Facebook feed and a few others along the way. He then posts the whole thing on Youtube, and now you are reading about it in a blog. Pretty cool stuff!
