indeed nothing is free, either one pays through selling one's valuable personal data (TW, FB etc), via annoying adverts, via a stake (HIVE, EOS) or via small transaction fees (BLURT!). One might imagine premium blogging services offered by BLURT blockchain, where these higher fees would benefit witnesses, reward pool, stake holders etc. think blogging services such premium markup, faster TX, promotions, higer res images, premium search engine. just thinking here.
