I used to be wary of ads (think: AdSense). I think ads, to me, had this stigma attached and then there were programmes that highlighted how people were duped into clicking ads that redirected them to the "dark alleys" of the Interweb. That was a couple of years ago.
Now, while still cautious, I'm feeling much more liberal in terms of ad clicking. I see an ad on AdSense, "hmm, photography site... looks interesting", *click*. The fear's not so much there anymore.
How many of you click on advertisements?
I mean, you're genuinely interested in the ad so you click on it and not because you're artificially inflating clicks for your friend.
