Where do I go? How do I search for something worthwhile? There's no central space to find it, compare communities etc. I was curious but now I am kind of put off.
It just needs to be posted as a main aggregator at https://join-lemmy.org, or even better, on the right hand side panel on every Lemmy instance.
I know this would be a centralized database of communities (which is probably frowned upon in the fediverse) but I don't think there's a sensible way around it.
Trolls, bullies and harassers though will have better access to you.
In principle this probably happens but the alternative is having no large vibrant communities.
I did this for a "dead" forum and after about a week of "squatting" there and posting for myself, other people started showing up and replying to it.
People should treat the digital silence of dead communities as an asset and free real estate to share their thoughts.
