Check out TimeTube, a mashup from San Francisco startup Dipity, which makes an interactive timeline out of any YouTube keyword. Videos are embedded directly into the timeline on the dates they were added. I’m a little unclear on what garners more emphasis within the timeline– it doesn’t appear to be number of views. Anyways, then you can grab whatever you make and embed it directly in your blog.
Would have been great to have this for our Rickroll timeline last month!
