I remember joining reddit when it had the old interface and thinking that it is super unintuitive and complicated compared to all other social media. This didn’t stop reddit from growing and i don’t think lemmy will be restricted by this in the long run. People generally are just not aware of the fediverse and how it works yet but they will get used to it.
The only additional step you have on lemmy is choosing an instance and honestly it does not even matter that much which you choose. I’m not saying it’s trivial but it is nothing that is inherently more difficult.
Reddit was really strange compared to everything else a few years ago. It only appears easy now because we are familiar with the concept of subreddits now.
No you cant, karma requirements bud, try making a new account and posting/commenting anywhere?
