Jason Calacanis isn’t too happy with Comscore numbers and Henry Copeland of Blogads seem to have a similar opinion of Comscore.
For the record, my colleagues and I have always found Comscore’s data to be hilariously inaccurate. As I recall, for a long time Comscore showed PerezHilton.com to have a predominantly male readership, even when our multiple different surveys and data-sources showed his readers to be 88-90% women.
I don’t know what Comscore’s data shows today, because frankly, I gave up caring about Comscore years ago.. As Jason says, Quantcast and Google do a much better job. link.
