This is simple: I don't collect any data about you. Period. No cookies, no graphic bugs, nothing. I don't ask for you to log in, to take a survey, or respond to a poll. You are free to peruse in peace :)
I don't know what information Chimpshack may or may not be collecting about you. I'd guess they track "aggregate data regarding patterns of use and IP addresses that cannot be linked to a particular user" blah blah blah yadda yadda yadda. I don't think Eric is doing anything funky, but if you want to be sure, you'll have to check into that yourself. Sorry.
The hit counter on the home page is provided free by Statsmachine (you may see a "contacting Statsmachine" message in your browser status bar if their server is having a slow day). I don't know what they collect about you, either.
