Although not a UI, @paulag has been offering a small incentive to power-up for a year now, and with the help of @yabapmatt, @steemcommunity for 39 weeks.

Encouraging and intensifying this action can only lead to good things!

Will Steemit offer any incentives to power up or charge a fee for features when Communities are initially launched? Eg. For promoting a Community, or to bid for popular community names? Communities are such a good opportunity to incentivize more power ups and create demand for Steem. I hope we take advantage of it when Communities are launched.

There's no immediate incentive, but it costs about 3 STEEM to create a community, and communities helps pave the way for further gamification. Communities themselves could choose to provide certain benefits for any criteria, including SP.
