I'm not sure, but I don't think it's all that apparent that people can build things here and join in on getting stuff built. That would appeal to a fairly niche but dedicated audience. And is one of the (dare I say it 🤢) USPs of nostr.

And yes, I'll bang on about Communities again lololol ('communities fixes this' ©️). People with followings who have increasingly been getting sick of platforms pestering them over content and censorship could see a good use of this. There is an example of one such group in here already.
