More Web2.0 stuff

In ResourceShelf I saw this post: 2.0 Worth A Look #3: Timeline, Nowsy, Calcoolate and particularly like the look of Nowsy. This appears to be a combination of aggregator and search engine., ie. you search for terms that appear within your chosen feed.
You can customise the look of the aggregator and some links are already displayed so you can see how it looks. One of them is YouTube and the first clip on the list was Evolution of Dance. Although I became a bit lost after Greased Lightning (it's a long time since I last went dancing) I really enjoyed this comedian's antics.
