Recently I experimented with having adsense advertisments on the chgc site, with the rationale being: it costs me money (to run that server) and time (to run the club web, membership stuff and mailinglists) and I don't get anything out of it except a Warm Fuzzy Feeling - which occasionally is very close to the Warm Fuzzy Feeling you get when some(body|thing) has peed on your pants.

Anyway, I thought why not try and see whether ads might work for paying towards the server cost. Hence, Enter Adsense, which claims to provide contextual ads.

A week later they hadn't managed to serve me one single ad (always only offering the community service ads - or none).

So, Exit Adsense: you suck.
