Rafael Ferreira @rff.bsky.social · 08/10/2026I really like idea 1, tho spam and clickbait might be issues. I am worried about private groups; if they succeed I expect the most interesting conversations will leave the public space, which will prevent new connections to form and slow down the growth of the network.
