The features are irrelevant what matters is the content infrastructure. This infrastructure exists elsewhere and delivers the content. There’s no reason for people to switch to something that does not deliver the content except being mad at reddit (which the majority don’t care enough about to follow through on).

The infrastructure that matters are the communities themselves and the populations of people that submit to them. You can’t just magically transfer them, there has to be a slow and steady build up over time. You need the dedicated early people to build the foundation that will then get you the later hogs.

The issue isn’t technology. It’s content and people. You don’t get the later people without the early people. It’s so easy to see that there’s a process of groups of people that should be targeted one by one after another. There’s a roadmap already laid out by multiple successful iterations of the same bloody thing historically.
