I'm trialling (and have registered) reddit as my new home page. In the past few days it has enabled me to find some excellent articles that I would otherwise have missed. It's written in python and is recommended by Paul Graham, a LISP programmer and essayist.
What is reddit?
A source for what's new and popular on the web -- customized for you. We want to democratize the traditional model by giving editorial control to the people who use the site, not those who run it. All of the content on reddit is from users who are rewarded for good submissions (and punished for bad ones) by their peers. You decide what appears on your front page and which submissions rise to fame or fall into obscurity.
