Alexa, you coulda been someone

I've been looking at companies who provide Web tracking data for the purpose of understanding how many people are seeing a company's message as it spreads around the Web.

This post really rips poor Alexa, who I thought previously might be one of the good sources of this data.

Alexa was all the rage back during the dot-com boom but what have you heard about them since Amazon bought them? Not much. I'm sure they had great plans back when A9 the next big thing, but that seems like ages ago.

The comments to this post really outline well the main problem with Alexa data: faulty sampling methodology based on the sad fact that the adoption of their toolbar is probably quite small and in niche areas.
