For some reason I've never thought much about it except as a waste of time, another cookie on my machine, and my pennies won't make a difference anyway. Then today I received an email explaining how it has been considered the comraderly thing to do, this click through on ads.
"Of course," says DW, and continues with "I do it. And I've always wondered why you don't have ads on your blog."
"Because with the number of readers, it would indeed be mere pennies."
I am not going to spend a lot of time thinking about this, and if I do decide to put ads on my site, I'm not going to spend any time justifying it. However, let it be known that I will henceforth take the couple extra seconds to click through on my friends' sites.
