I got a number of answers that sound very weak to me, and basically point to a “fail” of the fediverse in its own nature if threads joins. Kind of disappointing.

To me, the key idea of the fediverse is that it’s federated and should work as a whole, no matter who joins. Most of the answers below support the opposite. They are basically saying that the fediverse should stay within the “fediverse”, which is exactly what non-federated social media are doing. Meh.

Aside from the “moral” argument, can someone ELI5 what harm can a federated threads.net do on other users (like me) and/or instances?

I don’t think so, because forcing users to post means shitposting.

I can understand. After the initial excitement, the content is lacuster and scarse compared to reddit (due to lack of large userbase)

And what’s the way to reinstate those communities? They might have very valuable names.

Thanks for your story. I used both MATLAB and Octave, and while the language syntax is the same and most of the built in functions and basic toolbox functions are similar, Octave come short as soon as you start using graphics and more advanced toolboxes.

I flew Delta and they offered free internet for WhatsApp, iMessage and Facebook Messenger text-only messages. Better than nothing, but I suppose some of you here would have been able to access the full WAN through that.

I get your points. Thanks.

The way I use multis in Reddit is to create bigger topics, and I rarely see duplicated posts. For example, in Reddit I do not have a multi for subs /r/android1, /r/android2, /r/android3. However, I have a multi for mobile OSs, grouping /r/android and /r/iOS. Rarely do I see duplication.

That’s precisely why Reddit and Lemmy exist, they are content aggregators and people sort out the best content and comments by voting. If you are trying to make the point that I should deal with multiple duplicates posts on Lemmy in the same way I deal with multiple news outlets, then your point is equivalent to say that Lemmy is useless.

Well said, I agree with this too.

The problem is that posts may be exactly on the same trending topic, but not exactly the same. They could link to two different news sources for essentially the same news item. Or they could be a text or an image post about the same. Reddit mods would usually remove this kind of soft duplication within the same sub, and instead encourage to comment to one single post.

Merging multiple communities like in a Reddit multisub would not solve the issue of duplicated posts in one’s feed.

The “old” community was frozen.

“Our feeling, and our decision, is that while having multiple communities for the same topic is a key strength of the fediverse, we’re keen to avoid unnecessary fragmentation for existing members and confusion for any newcomers.”

The multi does not solve the fact that we’re going to see multiple similar posts on the same trending topic, with comments/discussions distributed among them. One of the things mods do on reddit is to exactly prevent this in each sub. Here, mods can prevent this in each community, but not solving the duplication in multiple communities of different servers.

Thanks, yes, I agree

I think I do understand it. One of my points above is one community decided to merge into the other to prevent fragmentation. Not my own words, sticky post on android@lemmy.world.

Thanks!

Agree, and I think hashtags (or similar) are very important unless you are literally just interested in the current toots only, or you check Mastodon every minute.

Most are twitter mirroring bots, which means it’s OK to follow but there will not be much engagement.
