Most are on LemmyNSFW. Note that they won't show up if you aren't logged in, so you'll want to use LemmyVerse to find them and subscribe from your home instance
Tildes is just too small. The obvious explanation for growth is all of the Fledditors (Rexit? I like Lemmygrants, but that really only covers people who came to Lemmy) looking for an alternative. People wanted a drop-in replacement for what they already had. Tildes didn't even have enough of a seed in their biggest subs, let alone their (very few) niche groups. Same for Raddle, Squabbles, etc. The only subs that made a significant migration to those are the ones that packed up, locked the doors, and left a forwarding address to anyone left - Similar to what r/piracy did, except that went to Lemmy (complete with instructions to ignore the federation questions)
As for Kbin, I think the bigger factor is coverage. As soon as anyone started mentioning people leaving for greener pastures, Lemmy was always the first thing mentioned. Kbin was always a second-place alternative, along with a few others. Since Kbin has the same confusion about federation as Lemmy, it didn't pick up a lot of people that bailed on the first choice.
Not that it matters much anymore, since Kbin is well-federated with Lemmy
Clients, no. We have no way (currently) to individually block an instance, nor would it be effective in preventing this problem. Threads users, as a whole, need to be blocked from the Fediverse, so that Threads is not viewed as a way to interact with Mastodon users.
Our particular instances can defederate from Meta, which would stop certain issues - but not the EEE concerns that are usually brought up. It has to be a widespread block.
Nah, coffee pots are strictly clients in the world of tomorrow. They connect to a (datamining) cloud service, and you control it through an app.
What's wild is that IPoAC was actually tested, and shown to have a higher throughput than the local ISP. Source
Face to face is not only unnecessary, but often counter-productive. You aren't likely to just already be at the same place, so one or both of you must travel to the agreed upon meeting place, just to deliver the bad news. It also often forces an unwanted and pointless conversation, and draws out what may be a painful subject for both people. And this assumes that it goes well- others have mentioned the risk of violence, extreme emotional distress, etc.
I (generally) oppose ghosting, but it can be done remotely.
Keep in mind that right now, all of the big names posting are paid content. It's probably not labeled as such, but they're all on Meta's payroll to make the platform attractive to new users. Will it take off? It actually has a decent chance. Not because of anything that they're doing, but because of exactly how badly Twitter is fucking things up right now. People want out, and most couldn't/wouldn't/didn't make the jump to Mastodon when everything with Musk started. This now looks like a viable alternative to them.
But no, I don't want Facebook to destroy this beautiful new thing I just found.
Because for each thing that "Everyone knows" by the time they're adults, every day there are, on average, 10,000 people in the US hearing about it for the first time.
(The alt-text is also particularly relevant)
There's also ELI5, which may be more useful in some cases.
I'm not sure that's a valid comparison. Tumblr was overwhelmingly porn, which was its biggest selling point. The only thing dumber was when OnlyFans tried to ban hardcore porn (Fortunately, I guess, they saw the light pretty quick and relented)
While Reddit always had porn, it was never the primary draw.
To expand on this, it's not just capitalism - it's greed.
The more niche your interest, the slower it will be to build content. Certainly the most popular communities are already overflowing with content, while others have no home yet. But it's all growing, and quickly. When LemmyNsfw launched, the only communities were the very obvious and popular ones. Those are now filled with a bunch of content, and more coming in constantly. But what's more interesting is some of the more...ahem niche communities that have sprung up there, and are now showing signs of life.
There are sites like sub.rehab that can help you find where your content has moved. Not all of them are in the fediverse, either. But you may need to lump some of it into broader categories until interest grows. For instance, emulation might be covered under piracy, or one of the other subs on FMHY or DBZero. It won't be exact, but it might be close enough.
You can also start your own community if you think there will be interest. Just be sure to prime the pump with some content right away to bring people in.
True, but Lemmy.world and feddit.cl (OP's instance) do not block it.
