There are few things the developers could do. For example, they could make the platform easier to use. Many people don’t even reach this place because they’re not that tech savvy or simple don’t care enough to figure it out. It’s much easier for them to just create an account and get started on Reddit or elsewhere. This leaves extremists with nowhere else to go and tech bros… which are the two groups that dominate this place. The process of getting on board and finding instances/communities needs to be easier. There needs to be something like centralized site/app that is easily accessible and shows all the different instances and communities in one place.
Decentralization isn’t left wing or right wing, that’s just a moronic analysis. Decentralization has a wide appeal but unless it gets simplified and standardized it will never become adopted by the mainstream. Places like Lemmy which are littered with gatekeepers like you doom this place to forever being a niche. If this place ever hopes of rivaling reddit, it needs to appeal to more than political extremists and tech nerds
