mrbarkeeper writes "IBM Research has thought about email and came up with a prototype of a better mail client. From their website: 'The Collaborative User Experience (CUE) team in IBM Research has spent nearly a decade studying email. Not only has email become one of the most pervasive and successful collaborative tools available, it has also become a key component of IBM's Lotus Software offerings. In many ways, email can be seen as a victim of its own success - users increasingly suffer from overload and interruptions as well as use email in a manner for which it was not intended.' Several ideas worth discussing, some good, some irrelevant. But still worth a gander for anyone who spends most of their day in their inbox.
