I have a good idea too, without ads! Profitable also but not a twitter or mastodon clone, more like myspace met reddit and a really pretty baby (great UI concept, i won't spill the beans), moderators get paid and moderation is federated. Most importantly it isn't some idealist utopian platform but built for profit while preseving freedoms and user consent and user data ownership.

I would rethink about mirroring real life interactions, real life has drawbacks and people can do real life in real life just fine.

I have many ideas though, and I am not motivated enough and I don't code for a living or have a ton of money and a desire to make sales pitches.
