Ie, i get friction currently when looking at alternatives not in "the verse". Eg Tildes, i have the same concern.
I wrote up about reddit alternatives here https://non.io/reddit-has-platform-user-misalignment , and one of the things I call out is that what we need is a better fundamental model. Federated approaches may very well be that, and if one "wins", I think we'll end up in a better spot. I personally prefer a standard hosting architecture along with aligning user and platform demands, as this comes with some benefits over a federated architecture. I may be wrong here though - each definitely has pros and cons.
As others said, make the frontpage a contentpage. See if you can seed some creators to post there.
