I have an integrated solution which might also fight spam, and which would relate to contact lists / social websites. I.e. if someone is in the contact list of one of your contacts, their email gets treated as not-spam, and if you had an automated ranking algorithm for email (emails with frequent correspondents go towards the top, email from contacts is second tier, newsletters go towards the bottom, etc.), it could go towards the top. Or, the email comes from the friend of a friend of a friend, it's considered to not be spam, and put in the middle.
I'm not suggesting you be able to see your contacts' contacts, but something akin to the six degrees of separation application in Facebook. This could get computationally intensive if you were checking for enough degrees of separation. But it's obviously doable, if the Facebook application can do it- and if it were too CPU intensive, maybe some people would choose to pay for the service.
This would also fight spam even if it were only applied in a small number of email inboxes. Because, if it sees that emails from an email address aren't in the first six degrees of contacts of any of, say, the first 10 receivers, it could inform ISPs that all future emails from that address are suspected spam.
This is the idea which is most off the top of my head, so be wary of it :).
Another idea- add a reddit-like button next to emails which lets you move stuff up and down in your inbox. This would serve dual functions- letting you sort emails and to-do items by priority (a right click on the button would let you move stuff up or down by 10, 50 places, etc.), and it would also tell your filter what you prioritize (which contacts, which key words, etc.- like, PG's filter might notice he likes emails with the SIP "Lisp" in it).
That wraps up my ideas that are relevant to PG's list, as far as I can recall. If anyone has any questions about any of them, let me know. I've fleshed out most of these much further than you see, I just don't feel like doing a 50,000 word writeup as a comment.
