An idea that I've been dreaming of (and kicking around some prototypes of) for a while now is a integrated archive of all the communications services/mediums I use these days. I have close contacts who I may interact with across 5 or 6 mediums in a given week - e.g. email, IM, IRC, SMS, twitter, comments on their blog posts. I'd like to be able to go into a contact list, click a buddy, and get a timeline of my interactions with them across these mediums. Google's gotten part way there in the last few years with email, Google Talk logs and Google Voice voicemails and SMS all being searchable from the Gmail interface but it's not as extensible as I'd like and the results quality (ironically) leaves a lot to be desired.
