I have just added Google ads to try to compensate a bit of my hosting costs. I have tried to make it as unobstrusive as possible, so it should not annoy. In case it does annoy you, you might want to give Adblock and the automatic Adblock Filterset.G Updater a try.
No more ads. they are just too ugly, and traffic is not that large.
Ads now look ok, and the site looks also good if you use an adblocker. I now get filthy rich from my ad revenue of $0.19 per day, wohoo!
