One additional observation is worth adding to this write up - self-voting has nearly no financial point for those who have no notable Steem Power.

Earning 54% APR on ~$20 of SP a typical minnow has after joining the site means getting about $10 per year - not something worth bothering to vote 10 times a day for the whole year.

The minnow's money game would be to vote on all the popular user's posts as much as possible, and I hope I'll get the time to look into that at some point (it is more complicated because one needs actual data to model the realistic expected outcomes here).
