There is a wonderful resource called reddit.com which has filled a need in my internet routines. Naturally, we will always have google - which allows a "pull internet;" Google is great if you have in mind exactly what you want to find. But it's nice to also have services which offer a "push internet" - where you can just go and find whatever is coming your way that day - and read up on hundreds of fascinating topics that you wouldn't have known about before. Reddit is just this sort of a service. And while the front page will often be full of crass jokes and absurdities and misguided passions - if you look through the list of smaller link sharing groups there, you can find some gems. This is a current list of my favorite groups there.
