Darren Barefoot pinged me about this, so here’s a for the record comment.
I don’t think this is different enough than what Gmail’s SmartLabels (it’s in Labs, turn it on) and custom filters do today. Robert Scoble has 1300+ filters in Gmail.
In essence, the summary of PandoDaily’s post is that the future of email is inbox management. Which I don’t think it is.
Lots of people struggle with email, but I think the mass market are never going to manage their inbox. What professionals need / will adopt is another question.
