steemians have elected delegates and these delegates are in constant contact/debates with the steemit devs.
So steemit is in touch with the community 24/7 if you have an issue/question or concern, please forward it to one of the top 20 witnesses : (use a memo field in a TX)
https://steemit.com/~witnesses
or pm them on steemit.chat
Super answer. Do the witnesses communicate directly with all the developers or do they communicate with certain staff members? A representative..
