Most of the time I do yes!

But as long as the big #s keep rolling in I dont concern myself with it really

Always checking referrals to analyze my promotion efforts...

Yes, I keep track who view my website..i used stat counter

are you kidding its like an obsession ! first thing i do and the last thing i do every day if check my stats of the most important sites to me, its good to see where people are coming from, one of my sites gets over 80% of its traffic through google, 5% yahoo and the rest though other sites. this is with 700 - 1000 minimum uniques a day. make interesting reading, especially some one comments on a forum about your site and everyone click through to it, you can get everyones views with out asking lol

I don't. I have too many websites to keep track of them.
I try my best to promote my websites but don't have the time to check where the visitors come from.

Hm
Not neccesarily.

It's a good thing to keep such a record..
