The world, exactly like the Internet, does not end at the US borders.
And yep, even though many US citizens seem to be on the verge of slicing each other throats, it doesn't mean the rest of the world should behave the same. Lemmy users should still be able to discuss freely even between people of varying opinions, or even of completely opposite opinions.
When you block someone, you can still see that they replied to you. I don't want to know of their existence period, that's why I'm blocking them and they shouldn't have a chance to respond to me period. It's not blocking if they can reply to me and I still see a notification that they did.
Not enough video game communities. I think that was a huge part of Reddits initial success. Even to this day I still search "Problem + /reddit" on google whenever I have issues in a game. Reddit often holds the core community off a video game. It's often detrimental to a games success to have a Reddit community. Lemmy has communities for some games, but they are mostly inactive or have only 10-60 users. So don't even have the latest patch notes posted.
Instances going down forever. - kbin, even though its not lemmy, had a more appealing UI to me and my little brother. We're on fedia now, but I only really use it to lurk when Lemmy.world won't load randomly. I don't think he even uses it at all anymore.
De-federation. - Beehaw caused several other people I know IRL to go back to reddit within a week. The timing was so perfect to wreck the API boycott that I'm almost convinced the Beehaw mods work for reddit. "Everything was broken" and now lemmy is dead and gone forever in their eyes, some even assuming the whole thing is literally gone now. They're not willing to try again.
The syntax of linking to users, posts, communities etc. is hard to keep a mental grip on. I know they couldn't exactly copy reddit's u/ for users and r/ for subreddits, but ! for communities and @ for users isn't as schematic. I think it's why you see it used less than on Reddit. And if you start to type a username, and an autocomplete window pops up, it inserts that format in brackets followed by a URL in parenthesis. To the right of the text box I'm typing in, I see, and I'll approximate this as best I can:
Ask Lemmy@lemmy.world
asklemmy@lemmy.world
Neither has the exclamation point reminding you how to use that feature. My bipolar ex girlfriend had a more consistent UI than that.
Linking to posts and comments is just pure moon logic. Follow me here:
This Post is stored on lemmy.world, right? Where is the comment I'm currently writing stored? on lemmy.world, or sh.itjust.works?
@kibiz0r@midwest.social commented on this post, I'm going to use it as an example. There are two buttons next to their username. Both have the hover over tooltip "link".
If I wanted to refer to kibiz0r's comment in some other thread somewhere else, which of those links should I use? I figure in most cases I'm addressing an audience of the entire fediverse not just my fellow sh.itheads, so why would I ever use the first link? What does someone from lemm.ee see when they click on either of those links? Do they get to see it through their own account on their instance, or do they get linked directly to another instance? This really breaks the idea of "one account, whole fediverse."
Can't filter out non-English communities. On any given day, I could scroll through my feed and a third of them would be languages I can't read. I wish I could, but I can't.
The default web interface is very poorly designed and looks uninviting. Sure, there are great alternative interfaces but people will be turned off before they could check them out. Also, it's usually the first thing you see when someone's sharing a link.
There not being an official app is also something that will confuse non-tech users.
Many instances have domain names that look invalid and/or like scam sites to non-techies. Dot world? Dot social? Dot [obscure country TLD]? There's also no guarantees that the domain will indicate that it's a Lemmy site. Both of these become problematic with sharing, as the default (? been a while since I've used the web interface) share function links to the poster's instance and not the community instance. A year and a half ago, the shared links section in my messenger was mostly a Reddit flood. Today, it looks like someone spilled alphabet soup.
Too many terrorist simps, too much mod abuse, too much disinformation, too many Tankies, discovery of communities is hard with how federation works and kinda requires third party apps.
If you complain about a technical thing, you'll end up having to justify every square inch of your existence in order to prove your complaint isn't just user error.
It can be hard to find the right community to post a link in. Figuring out the rules and knowing who's reading them (and sometimes what they're really about) might cause someone to give up. (Especially when people complain about 'this isn't the place for that' without stating the better alternative.)
Nothing is deleted, just slightly obscured, and some apps don't even do that. Child porn, illegal revenge porn, hate speech, everything is stored forever.
