intertwingly

Ben Smedberg: Frequently I will get the same blog posting via Planet Mozilla, an individual blog feed, and even Google blogsearch feeds. I really desperately want my feed reader to know that these are the same post and display it once in my inbox, instead of multiple times.

It would help if Google blogsearch would retain the ids from the original feed (perhaps they could provide this information in an extension element); either that or if Google blogsearch added source elements [example] to the feeds it produces.
