This question is especially for people who have joined in the last week. Have you used other fediverse platforms or is this your first time really using one? What do you think of it so far? Are you aware that you can comment on Lemmy posts with a Mastodon account?
I mean it’s not any different from how email works. You decide on an email provider that you want to use, and then you can send messages to other people who use other email servers. It think it just seems difficult because it’s different, but it clicks once you get into the right mindset about it. If Lemmy becomes big then a few larger providers will probably surface and be the go-to for non-technical people (c.f. GMail, Yahoo Mail, etc).
