if you can make your division thematic you'll see your adsense revenue go up a bunch. imagine people looking through the possible spots to plop ads, the better segmentation available, the more focused they can choose, they higher they'll bid. placements make it all possible.
yesterday i was configuring a couple of new placement ad groups and was looking for space for an energy drink. i came across tons of body building sites - and i wished they all had a segment called supplements or dietary aids so i could really use a high bid.
i think webmasters tend to think of placement, and less so about marketability of certain subpopulations of their visitors.
see here: https://www.google.com/adsense/support/bin/answer.py?hl=en&answer=32614
they demonstrate both Custom Channels and URL Channels in the above help file. imo, the URL channels are a great way to increase your adsense income by permitting better targeting on the other end for your space. the better appropriate sections can be targetted, the more valuable your space is too advertisers and google, and therefore to you too.

yes, I've seen things a lot more from the adwords perspective and as you say, the finer the niche you can find placements for, the happier you are. I have about 30-40 sites targetting me as far as I can tell, so I might spend an hour splitting my site into 4-5 clear sectors. I've only split it into two halves for now.
