Sometimes AdSense can be seen as an information panel — more than a place for advertising. For example, on my Rehal blog which talks about booksphere, I saw several interesting ad words appear, i.e. Book Finder, Used Books. Having clicked, they pointed me to useful sites even I did not intend to do transactions.
Do I harm AdSense mechanism when I click my own AdSense merely because it is interesting enough for me?
I hope not simply because I did not intend to abuse.
[Update 2 Jan] Information from Google AdSense,
Please note that clicking on your own ads for any reason is prohibited, to avoid potential inflation of advertiser costs.
How if those links are really interesting?
