I thought I was alone in helping the competition etc.
I know some of my competition is in this very forum and go to PubCon. One of them even posted about something very close to my site once, short of posting the URL, it was very amusing and really hard not to comment. Whether they know who I am or not, I have no clue, but it gets really interesting at times!
Not that I consider myself an AdSense guru, I just know what I know if you know what I mean, and it happens to make coin. However, knowing who's reading what I'm writing means I often have to be very cautious about what I'm saying. Which means some things I could share get watered down or not shared at all because of prying eyes.
