And thus ends the brief experiment with adverts. I've reconsidered after capricious rules were presented by Google in a seemingly unending cascade; that, plus anyone may object to the content of an ad at any time and have them pulled until I "appeal" Google's decision. Yeah. After having twice to appeal a Google decision to withhold ads from the site, for reasons that they will not reveal, I realized why the corporation and our government get along so well.
So, back to normal.
