Would you try harder to save if there were new Status incentives?
Would you put more effort into your OhmHours if there were more incentives?
There are a lot of Platinum users now, many of whom find 40% an easy goal.
Maybe add gemstones for higher status? Example:
Emerald - 60% savings - 100 tokens/OH.
Ruby - 70%, 150 tokens/OH
Sapphire - 80%, 200 tokens/OH
For me, this would add to the OhmConnect experience, which I participate in like a game, trying to beat my own "scores", but you don't have to be a nerd to appreciate some extra tokens.
Just a suggestion, but I think it would look great on the dashboard.
