This might be why a federated system like Mastodon or GNU Social could win out over a fully decentralised one like torrents. Because for a lot of people, the individual services that act as network nodes could work like Facebook/Twitter does now whereas more technically advanced users could host their own nodes instead. Which reminds me. Why are all these decentralised/federated services focusing so much on trying to replace Twitter? I mean, maybe it's a silly question, but replacing Facebook, Instagram, Reddit or any other number of services would be just as valid a goal. Why is every one of these systems seemingly going for the microblogging market in particular?
