I told somebody I know who knew about Reddit's API changes about Lemmy. He has a master's degree in Computer Science and works as a software engineer. But then, he told me that it's too confusing to get into, even for someone like him. This is great feedback and I hope that these issues will be fixed in the coming months.
The fediverse is not suited at the moment to fixed mindset types.
Personally, I find that refreshing. It reminds me of my earliest interactions with the Internet on BBS. The web for a long while has felt very consumerist; first curated spaces becoming walled gardens and then the subtle shift from web services as products to our attention & data as the Internet's main product. We lost the magical sense of exploration and experimentation that made the early Internet so special. The fediverse is the first instance (pun half-intended) I've come across that speaks to that spirit.
