Hello @berniesanders. nice to Steem you! A topic that comes in mind, related to the Witnesses universe and the clarity of speech on Steemit, is the fact that all videos uploaded on DTube disappear after a maximum period of 3 months... How many Steemians know that the IPFS storage isn't free of charge, and that DTube currently doesn't pay the due fee? That's why, for instance, a French Witness recently took the responsibility of setting up his own IPFS node (supporting its cost), to "rescue" the French-speaking videos previously posted on DTube.
It'd maybe be worth an article on its own.
