Good idea,
Also, good idea will be to make some steemit-credit card what will help regular steemians to cash-out their assets without making lot of passes on exchanges.
And maybe need to make some interactive application inside steemit platform what can burn some amount of steem or sbd. something like change theme, make some achives, games and etc. where the accepted funds will be automatically converted and send to @null account.
but I'm not sure what it will have a big effect.
