I understand concerns about fragmentation, but recently, I have been more and more in favour of “why not both” as an approach. Basically: One de-facto “central” community, and many local communities. Main reason being, that this will help the Fediverse grow without losing it’s “soul” so to speak. Where - hopefully eventually - there will be those central communities with a reddit-like experience for the topic, and then also local ones, where smaller communities around the topic, without the traps of large, “mainstream” communites, can form.
If you don’t have any money, maybe you can also help if you have a bit of extra space on your HDD - by mirroring some things (especially in the torrent form and seeding), it will at least be one more redundancy of some things in the worst case.
EDIT: Turns out, there is a [or at least one] tool for it:
