“Decentralized network of forums” is probably the best way I’ve heard it described, as an elder millennial who grew up on multiple disparate forums.
The email analogy doesn’t resonate with me because I, as a Gmail user have less than nothing in common with any other Gmail user. On the other hand, the idea of being able to log into my car enthusiast forum and interact seamlessly with people from a video game enthusiast forum is much closer to how I think the ideal Lemmy experience would go.









I’m not going to claim to be a privacy/security expert here, but I think the question is “safe from who/what?” Privacy is a sliding scale with diminishing returns, so you need to set your expectations according to the level of effort you are willing to put in.
If you just want to not be tracked/profiled by commercial big data or standard governmental operations, then an old phone with no sim, wifi/bluetooth turned off, and using wired headphones removes you from a couple tiers of lowest-hanging fruit.
But if you think someone is specifically and actively tracking you in particular, that is a whole other question.
