I’m experimenting with some new ad networks to see which ones can bring useful, contextually relevant ads without annoying the bejeezus out of us all.  You may see some pop-ups, etc. over the next couple of days as I play around. Stay calm; pop-ups annoy me as much as they do you, and I’ll curtail them as soon as I encounter them.  I spend as much time on this site as anyone, after all.
