As Mastodon grows, at some point there _will_ be a meltdown of some big instance into which tons of people put their trust and then the admin turns out not to be trustworthy (like the MtGox incident in Bitcoin). Even if it's a few hundred people affected, it will be major negative news.

People need to be educated about the role and power of instance admins.

@hisham_hm ehh I trust the French teenager in charge of mine...jk, but in all seriousness the ability to backup, export and import profiles from site to site would be a good feature.
@metapunk you can import/export follows/followers lists to/from csv, but the process could be more automated. There's room for development in clients and tools for this too.
