This is a really cool service and something that I have been thinking about lately as a cool business to do. Zemanta is like a blog assistant, as you type it is searching for stuff like images and content to add to your post. One thing that I have learned while having this blog is that images (not surprisingly) make the blog and posts a lot richer and a much better experience for the reader. I hope that these guys integrate with Tumblr ASAP.
Another idea I had for Tumblr (already sent it to them) is to have a section where I can put ideas and notes on future posts. There are some days when I have 20 ideas to post and no time and other days where I have lots of time and nothing to write about.
Anyway I think that Zemanta if executed correctly will get very fast traction.
