I don't think so. Displaying dollar can be misunderstood, as I suggested here:

A large portion of socio-psychological hardship in Steemit has come from reward distribution. People sometimes compare much smaller payouts than the bright past in July when trending posts easily got over $1000 (SBD). However, as matter of a fact, rewards in STEEM has not changed muchand what has changed is STEEM price denominated in SBD.

STEEM is a share of Steem blockchain, and can be considered as a reward point in Steem ecosystem, like Karma of Reddit or Marking of Poloniex. If we can make people to think the reward as a perk, at the same time make them free from money value, Steemit would be more enjoyable and less stressful.
