I've come accross at http://www.popuri.us/ ,which shows Technorati inbound links, del.icio.us bookmarks and the number of bloglines subscribers. Looks like a cool and usefull tool.
Good idea. Seems like many people thought so
NOTICE: Sorry, due to the tremendous amount of requests (hint: Techcrunch, Digg, del.icio.us, Lifehacker), a couple of services have banned popuri from fetching results. I hope to have this fixed in the next couple of hours.
