What if you logged into "MySuperDuperTwitterSummary.com" and everytime you hit your home page there, it gave you a summary of everything you missed since the last time you hit the home page, organized in a one-page, above the fold format. Links at the bottom would take you to previous reports. The challenge would be two things - on the back end, summarization/threading/categorization and then on the front end presenting an effective information design. I think you could get 90% of the way on the backend by leveraging hashtags. Anybody know of something like this that already exists? I have to confess I am completely swamped by Twitter and don't keep up either.
