In case you've not heard, google released buzz this week.  Buzz is integrated into gmail and is meant to provide a quick and easy way to share pictures, links, and chat with people.  When enabled on your account it sits unobtrusively underneath your inbox.  

Last week, Twitter released a feature that has changed how the service works for everyone.  The feature is called 'twitter lists'.  Twitter lists are curated lists of twitter users created by other twitter users.  The lists can be private or public. 

Public twitter lists is what I'll be referring to.  Public lists enable you to 'follow' everyone on the list without really subscribing.  When you 'follow' the list, it shows up on your twitter page it doesn't clog up your timeline.  You only see the list members twitter messages when you click on that list.

Here are a sampling of some public lists:

The website http://listorious.com/ provides a neat way to search for lists that match your interests.  

http://www.vobios.com/twitter-lists/ is a listing of the most popular lists out in the twitter sphere.

Using twitter lists enables anyone to get value from twitter without a lot of work.  It used to be quite a chore to find people to follow on twitter.  Not any more!
