I think there will need to be a re-invention/ re-write before the ‘real’ lemmy happens.
The issues around discovery, identity and communities being attached to a server, and how this impacts the math of the networking aspect of the whole concept are really what is preventing Lemmy from not only beating social media like Reddit, but representing a major improvement. The project has grown enough to make that kind of re-investment of time more palatable, but as lemmy currently stands, the protocol is in the way.
