Would be kewl to have a card where a blockchain address and probably an action could be rendered in a tweet. The card could look chart-stylish, assigned with the $currency logo and a call-to-action button. Metatags would be added to the linked URL source, but a linked account should be verified (write twitter ownership) on the used blockchain.
A bitcoin (or twitter-own altcoin [$DASH, $ETH, $DGB, $STEEM, etc.]) address on twitter-profile, would enable some payment possibilities. Connected with $LBC, authors could earn money and media requests (witness content for CNN, etc.) could be handled easy and automated.
