Long ago the saying was "be careful - anything you post on the internet is forever". Well, time has certainly proven that to be false.
There's things like /r/datahoarder (not sure if they have a new community here) that run their own petabyte storage archiving projects, some people are doing their part.
Consent-O-Matic is amazing, highly recommended.
It's buggy, but I'm managing. Weird things like having to press the "Subscribe" button twice. I'm assuming most will be solved when traffic stabilizes.
The federation is.. strange. Confusing when I click a link to another instance when trying to subscribe to a community, but also kinda cool how it works. I'm not sure federation should really be a concern for users, but time will tell. I'm sure it will only improve.
