This is natural evolution of all protocols, so it’s nothing to be concerned with in the long term, imo. Go back to Usenet: nothing but data hoarding nerds. Back to TCP/IP, nothing but protocols devs. Back to RSS, IRC, etc it is always the same story. In this case it’s just that the same community who were first to #Bitcoin (not crypto, btw, that’s a common misunderstanding, long story) were also the most motivated to build a better, censorship resistant means to share and communicate.
The expansion of content and conversation will happen naturally, it just requires the first stage of those willing to take the risk, and post the content that others will want while the network for those things is still small.
There is a bigger hurdle, but also far greater benefit to being early in the network. So post whatever you are interested in and you might make a lot more of a difference than you might think. 🫡
