If this goes anywhere, sure. Traffic jumped a LOT faster than I'd expected, so I'm running ads briefly to try to get a feel for what their impact will be vs. costs. Heroku is a nice platform, but it's pricey, especially for a hobby project with no monetization strategy.

Advertising figures gathered at this stage and traffic level will be relatively meaningless compared to something larger so you will have to re-test later if you want to get a real feel.

Likely CRTs and income (and ECPm) will drop off sharply as it gets bigger.

Yeah. I realized that about an hour in, and turned them off for the time being.
