With the promises of AT Protocol I wonder what the reality of starting your own competing site to bluesky would be if it were to become as popular as Twitter. I've also been looking into LBRY too and have the same question in regards Odysee. I'm sure we won't know until someone tries. I have a feeling there might be some unforseen network effects or barriers that build up over time to prevent someone from coming along with a better site. I'm just curious to see what they are and how insurmountable they might be.
