I see blurt charges a .4-.5 fee to make a post. Maybe blurt isn't a good platform to do development. This reply will cost about .08. It's not that the 1-4 sats will kill me, but a good dapp could make hundreds of thousands or even tens of millions of posts. comments, custom_jsons and the price of blurt, if ever used like that, wouldn't stay at 8 sats forever.
