I just wanted to post a brief note about a cool, very new mashup I ran across via the Delicious Popular bookmarks page, Expialidoci.us lets you look at tag clouds from your Delicious account over specific time periods using a sort of time frame selector similar to the one I love in MeasureMap, but much simpler in design.
This is still early, but a good idea – am looking forward to seeing how other people use it and how he evolves the concept. Have some other ideas here, but no time to write about them now…
