Click on the image to see the slightly larger (and better in-focus) original on Flickr. And take a look at the comments there to get a sense of who's missing from this visual list. I love the creator's response to some comments: "the logo map's a beta, too."
A number of these logos are of names that are already getting quite well known among a broader and more mainstream audience beyond the tech evangelist arena. Names like Blogger, FeedBurner, NewsGator and Delicious. Which of the others will become as familiar, I wonder, and how soon.
