- not all people buying FB ads are experienced marketers
- companies throw tons of money at ineffective ads, that should be obvious…
- we have no idea what the ratio of "successful" to unsuccessful campaigns is
- even if that ratio is negative, Facebook is still one of the only remaining "games" in town, so people _will_ continue throwing money at it. “Least worst” is a fine and lucrative place to be in.
- can we just get over this idea of rational economies, by the way
- marketing is less of a science than a craft, and all the implications thereof
