The problem with the Internet is that I might run into someone who disagrees with me, and I'd have to consider my opinions in light of theirs compare them to Hitler. Thank god there's a tool now to filter the Internet into things I already believe.

It's called Persai, and I guess it could also help overloaded web users, especially those with a list of RSS feeds and Google News alerts, whittle down their massive to-read lists by filtering out irrelevent info, but that's not what my friend Paul Boutin did when he tested the program for Slate. Instead, Paul taught Persai to hate Barack Obama as much as he did, serving him only negative articles about the candidate. The program's in closed beta now, and the makers are swamped with account requests, but you may as well sign up and bide your time until the public launch reading just four blogs and a Facebook group.
