I've used this site for several months, but I just realized that I haven't yet posted it to the blog. Here it is:

http://del.icio.us/
from the web site:

del.icio.us is a collection of favorites - yours and everyone else's. Use del.icio.us to:

• Keep links to your favorite articles, blogs, music, restaurant reviews, and more on del.icio.us and access them from any computer on the web.
• Share favorites with friends, family, and colleagues.
• Discover new things. Everything on del.icio.us is someone's favorite - they've already done the work of finding it. Explore and enjoy

Here is one page that I visit every day: http://del.icio.us/popular/programming
By visiting this page, I get to see what the rest of the computer programming community is talking about and visiting. It's an easy way to stay up-to-date on the latest trends.
