Alexa is this great software/service that gives you information about how people use the internet. Wanna see how many people read your blog? How much more popular is facebook (15) vs. hi5.com (14) or youtube (4)? I never really use Alexa. I'd like to, but I'm on a Mac.
Now this is just lame. On the internet of all places. I thought we grew out of "browser segregation" after web 2.0? I think this is a bad business decision. Now consider the popularity of Apple.com (89) vs. say Sony.com (913). Hmm... I wonder if I should install an alexa sidebar widget?
