Agree that it shouldn't be so complicated. I see that as a major flaw of the platform that will curtail adoption, but who knows, maybe one will win out over the others?

In any case, my understanding is that you can't log into the other instances with your username from lemmy.one, but you can read posts and interact with communities on different lemmy sites. For instance, I'm commenting from lemmy.world on a post you made using lemmy.one at a community hosted on lemmy.ml, but we can both read each other's comments, and so can people that signed up on other instances like beehaw.org.

You should never have to go to the actual websites for the other instances. Just like email, you wouldn’t expect to be able to use your Gmail account to log into Yahoo, right? Use lemmy.one as your homepage and browse everything from there. From there, you can use the Communities section to search/browse communities hosted on any instance, including Beehaw and lemmy.world.

You don't need to create multiple Lemmy accounts. You can search for and find and join subs from lemmy.world on your Lemmy.one account. it's not instantly intuitive coming from Reddit, but once you make the connection to the other subs on different instances its established for you

It will get better quickly—there are people working around the clock on apps and improvements right now. This isn’t like your normal social media site where they can use seed money and advertising to buy the best infrastructure right off the bat. This is a grassroots effort to make something that can evolve into a unique and independent service.

If we all stick it out with alternative options like this right now, we will be looking at a much freer future for online communication later. If we get annoyed and go crawling back to the capitalist overlords at FB/Twitter/Reddit, then we give them everything they wanted in the first place, and the internet will take one more step towards being a walled garden casino of ideas.

Your handle does work for all of the various Lemmy servers. But to access them it's like your email, you wouldn't log in to your Gmail account from Yahoo. Yahoo has no idea what your Gmail username and password is. So how can it let you in? And like email because both servers speak the same protocol you can interact with other users on other servers just like if you had their email address.

In your case lemmy.one is your email server so to speak. You can access any other Lemmy community or set of communities on another lemmy server by searching directly for their address on your home server or if someone else has interacted with another server already that server's communities will show up in your home server's All list and you can see those posts there and interact with them as if they were local to your home server.

Im talking to you from a lemmy.world account right now. Whatever instance you chose to create your account with is the website you need to go to each time you login. From there, you will still have access to search comment etc with any other community through your current instance.

You’re successfully doing it right now, commenting on a post from Lemmy.ml. You don’t need to log in to other instances, like Beehaw, to comment.

Are you on mobile or are you using desktop? The mobile app is definitely still in development so it's missing a lot of those QOL things that you are missing.

For me it's been helpful to use that fediverse search tool, and copy and paste it into the search. Seems to work better on desktop. I've got a decent feed going today, but it's definitely a work in progress.

Your handle won’t let you login on other instances but you can follow communities on other instances from the instance you signed up for.
