I thought one of the advantages of the Fediverse was to have one account but access to many services. Is this possible just not common? I already have a Lemmy account and Mastodon and I didn’t want to start making more just to try out the other services.
Common misconception by Fediverse newbies: “Fediverse” is an umbrella term for a bunch of decentralised walled gardens. Like, Lemmy only connects to Lemmy, Mastodon only connects to Mastodon, Pixelfed only connects to Pixelfed etc. And if you’re on Mastodon, and your Facebook friends join Friendica, you need a Friendica account to get back in touch with them.
In reality, just about everything is interconnected with everything. No matter what it is.
You can use your Mastodon account to follow people on Pixelfed, on Friendica, on Misskey, whatever.
That said, having a separate Lemmy account makes sense because Lemmy/the Threadiverse is somewhat special in operation. Also, it’s all about conversations and groups, and Mastodon doesn’t understand neither. And starting a thread on Lemmy from Mastodon is not as straight-forward as starting a thread on Mastodon from Mastodon.
