But even then, there are weird, unexpected dynamics.
For instance, pictures of my person tend to receive more reactions and replies than pictures of my dinner, but the latter gets lots of zaps and the former gets none or only a couple very small ones from some people doing OnlyZaps.
Should I respond to the financial incentive and never post pictures of myself and post lots and lots of pictures of food? Probably not. There's some weird effect on display here, but I know not what.
The zaps, and lack of zaps, are providing information, but how to interpret it?
