Steve Rubel thinks that ComScore is going to be hurt by the Web 2.0 metrics it's in the process of developing which I wrote about it earlier today in ComScore working on Web 2.0 Metrics.  Rubel says:

"…..Further down in the piece Dr. Magid Abraham, President and CEO of comScore Networks, added: "While page views will not altogether cease to be a relevant measure of a site's value, it's clear that there is an increasing need to consider page views alongside newer, more relevant measures." Abraham, however, doesn't say what that solution is. The reason could be such metrics could have severe ramifications for comScore's business model, which feeds off a hit-driven economy that's dying.

Comscore needs to wake up and realize that we're in a Long Tail world where top 10 lists matter less. Marketers want to know about the influence circles within the niches that matter to them - and those niches are often tiny. The time is now for comScore to open up to the little guy. "

I have not thought through that far - it seems to be if ComScore is working on Web 2.0 Metrics that's an admission that it needs to and it's present rating system is inaccurate.

Quantcast eating ComScore?  Really?   Are there companies really going after the same customer?  Look, maybe they are.  But Quantcast is a small startup right now - most of it's data is not very accurate (at least, not yet).  

If anything, I think QuantCast and Google Analytics ought to be together - meaning Google buys Quantcast and together - THEY eat ComScore.  That would be totally fine - but I don't think QuantCast's offerings are all "there" yet and there's many smaller sites (the little guy) that Quantcast does not yet have any data on - or so little to be almost useless.   Same thing with Compete.  But then again, I don't think ComScore is keeping track of the smaller niche sites either.

I guess what's really different about Quantcast is their technology and approach are probably much better suited to track sites than ComScore - but that's just my opinion.
