Please make me one of these: Universal read count

I see information in many streams, email, IM, twitter, RSS reader, etc. Unfortunately my brain isn’t good enough to remember everything that I have already read so I regularly find myself going to the same piece of information more than once.

Within each stream I’m unlikely to go back more than once because I get visual indicators that I have already read it. The main problem is between streams. That’s not to say, though, that people won’t send me the same piece of information more than once in the same stream.

I’d quite like a service that handled the read status for me, across all of the streams.

I should get a visual indicator that a link in twitter points to the same content as the blog post in my RSS reader, and they should both show anything that I have already consumed from a browser. Oh, and while I’m at it, it needs to do that across any one of the devices that I’m likely to use, and it needs to handle shortened urls.

My RSS Reader (FeedDemon) does a reasonably good job of keeping the read count in-synch across devices, but nothing between streams.

What I am looking for is to be able to mark parts of the Internet as “read”.

I’d also like this status consolidation capability to be searchable, especially by date. I am reasonably good at remembering when I read something, but not so great at remembering where I read it.

I’m sure there are a load more functional requirements that I would surface if I had time to think about it, but for now, this will do.

Has anyone done anything like this?
