I've been keeping my eye on Zemanta because they make a handy plug in that reccomends images and articles for bloggers. So when I'm composing this post, there is a widget on the right side that has applicable pictures and other articles I can link to. It makes writing this much easier because I don't have to Google a bunch of images and track one down.
They are now powering content suggestions inside of Gmail. This is going to be really handy for spicing up emails but the big picture is this company is laying the groundwork to disintermediate Google on a small percent of content searches.
Zemanta pushes, you go to Google to pull.
