I dug around a bit in the Google adsense doc and found that there are some tags which I can place around specific content to signpost to google that it should focus on that data.

<!-- google_ad_section_start -->

...

<!-- google_ad_section_end -->

So now, there’s much more of a focus on ‘surround sound’ advertising… which is probably more appropriate than all the ‘choral singing’ advertisement that was popping up before (choral singing was still a little appropriate but not as much as surround sound hardware ads).

That said … I still wish I could tell Google ads which of its ads I reckon my users is more likely to follow. It wouldn’t be hard to implement … just a little widget on the side of the Google ads bar where I do a thumbs up or a thumbs down on wether or not I think it is appropriate for my users. (I know that ads differ according to what country you are from … but the nature of what is being advertised is still the same ).
