It's a new milestone for our third most popular API. YouTube went past 500 mashups, a distinction shared only by Google Maps (over 2,000 Google Maps mashups) and Flickr (about 550 Flickr mashups). Earlier this year we chronicled the Top 10 YouTube Mashups of All Time, so we'll instead take this as an opportunity to share some of our recent favorite YouTube mashups.
Dragontape (today's mashup of the day): Create online video mixtapes to share with friends. Search for artists or songs on YouTube. Drag results into your list to create your own mixtape. More at our Dragontape profile.
Music Favmap: A map of the favorite music of Last.fm listeners. Circles to the right of the map have more plays per listener. The Y axis shows chronology, with the oldest tracks at the top of the chart. The larger the circle, the more plays the artist has received. APIs: Last.fm, YouTube. More at our Music Favmap profile.
uMapItUp: uMapItUp.com is advanced mapping software based on the Google Maps API coupled with the Youtube Data API.
