Played around a little bit with Dipity tonight. Dipity is a pretty cool tool to develop an interactive timeline on topics of your choosing. The example below (cramped by my choices while playing with their advanced embedding options) includes entries from this blog and activity from my Pandora account.

I could also include events I choose to add to the topic directly, events from other related Dipity topics, any RSS feeds, Flickr account activity and more. The entries can be viewed in a timeline, a list, flipbook or geographically. My Dipity topic invites comments as does each event when viewing the details of the entry.

Here are some more samples of what can be done with Dipity. These are actually newly spawned services from the Dipity crew.

There is even Archaeologist, the Digg Dipity (just had to say that). Dipity succeeds in conglomerating diverse content in a visually informative manner.
