Web3 became a marketing term, doesn't even really have a clear meaning, but it's used as a catch-all word for blockchain-related things like NFTs, cryptocurrency projects, etc. But most of those are not truly decentralized, whereas Lemmy and other fediverse projects are.
In addition to what's been said already - the community-specific wikis and megathreads. The amount of information I could find there about sometimes very niche topics was amazing. Hopefully something similar will be possible with Lemmy.
Yes. To add to this, if an instance suddenly changes its rules (e.g. in response to the influx of new users), I have to either adhere to those rules, or abandon my old account. I think allowing migration should be a priority.
Yes, we'd like more information on this please. I chose this instance from this list partly because of the name, and partly because of the lack of restrictions, it was marked as "adult" in the list.
Does no NSFW mean that we can't view anything NSFW with an account on this instance? Does it mean just porn, or anything considered NSFW (if Lemmy makes that distinction, I'm not sure)? Essentially, what does it mean in terms of restrictions?
