WP Marketer is a wordpress plugin, that MIGHT be useful to bloggers on our side of the internet. This is a mainstream plugin (non adult) that might work for our purposes.
Supposedly you can set keywords in your text, that will be linked to a sponsor URL you designates automatically.
THIS IS THE PLUGIN DOWNLOAD & INFO PAGE.
DISCLAIMER: I HAVEN’T USED IT, USE AT YOUR OWN RISK.
Note, not sure if it is 2.7 compatible either.
