Share My Web Statistics?

Michael Arrington at Tech Crunch announces that Google Analytics now lets webmasters share data with other Google products, and suggests that they should let us share web statistics with everyone, a suggestion that I find a little disturbing.

Like it or not, web marketing is cutthroat, and search engine optimizers are always looking for an edge on the competition — open web statistics are an invitation for somebody else to eat your lunch.

Personally, I like Quantcast, which provides public statistics about the readership of web sites that are useful for advertisers and others, but that respect the privacy of webmasters and users.
