Mash-ups & Remixes – these are the words that will characterize Web 3.0.
With the proliferation of APIs, many public facing, we are seeing an explosion of API mashup contests. Where people can take your data and do what they like. I posted about the IfThisThanThat site before that basically allows you to take any public facing API and make it work for you. http://ifttt.com/wtf . The web is truly programmable. http://www.programmableweb.com/apis
Today, I stumbled across NewsJack.
Sites like NewsJack (http://newsjack.in/) and even most browsers, allow you to “remix” sites on the fly.
