Even with consolidation going on left and right, the galaxy of sites that make up what we call "web 2.0" is expanding at a frantic rate (or perhaps that elusive goal of being snapped up by a bigger fish is helping to drive it). So how do you keep up with this ever growing array of web 2.0 sites? The answer: via the ever growing array of web 2.0 lists.
A little over a year ago, Richard MacManus posted his List of Web 2.0 Lists. Just 13 months later a lot of those links are dead, or no longer being updated, and there is a whole crop of new sites that we can now add to our arsenal. Below I will endeavor to update Richard's list with new sites and those that are still in business.
