In the interest of full disclosure:
Last month, I earned a total of $2.01 via Google AdWords ads placed on this blog.
To date, I have earned $23.56 from ads placed on this blog.
I have earned an average of $2.14 per month I have been on the AdWords program.
Since it seems that it will be ~35 months before I receive a check from Google, I am not seeing this site as a financial conflict of interest. [grin]
