OP, FYI I pinged you on this post but it was probably drown in the replies to your posts: https://lemm.ee/post/55244676
If you want to try out your approach (Photon as default, probably some communities hidden from the All feed), feel free to create a community dedicated to that project. You can probably promote it here and on a few other communities. The biggest challenge is probably going to find an admin wanting to give this a try.
I wanted to do something similar a months ago ( https://lemm.ee/post/52588852 ), but no admin was interested. Maybe you'll have more luck.
Thank you I appreciate all the input, I won't have the time or energy to drive something like that.
I can get behind a cause like that and help push it, but won't be able to lead.
I'd love a place where there is no politics, it might also be appealing to many and I think it should be the default.
