Thanks @nepd. That would be another interesting variation of the feature; I think I would prefer if the STEEM / SBD was destroyed (as to benefit all holders of STEEM), however it could be split multiple ways, where tokens used to charge up content on Zappl can be used for the following purposes:

• 1/3 of the tokens are burned (taken out of supply)
• 1/3 of the tokens are used to buyback ZAPPL UIAs and take them out of supply, increasing the valuation of their token
• 1/3 of the tokens are retained by the Zappl team to fund their efforts.

Since the Zappl team can specify a percentage of post rewards to take a cut from all Zappl content anyways, I'd prefer to see 50/50 between burning and buying back ZAPPL assets instead; this has the added effect of incentivizing ZAPPL UIA holders to "charge" content on Zappl and also increases demand for holding ZAPPL UIAs.
