Blogging my way through New York City

I find this site kind of spooky. " A map of the city that shows where the bloggers are, organized by subway stop. Find out who's blogging in your neighborhood!" NYC bloggers
It lists the bloggers location as well as the actual link to the blog site. People have to submit the form to get on this map...am I the only one that this makes nervous? At least they do no give out the emails.
