Eventhough, I don't really like the idea of using Bitcoin Blockchain other than for Bitcoin transacion, but it's a free world and if you want to do that you can do that. But I think, it will be more attractive if you can at least provide a whitepaper of your product, I saw that you already plan the technical details, so writing a thorough whitepaper wouldn't be a problem. Not just more attractive if you are trying to recruit people, they need to understand your product in details, so they will be sure to know what they are doing and if they are capable of doing that.

I mean for example if you are looking for a developer, there are so many programming languages out there, and I doubt that there everybody knows all of those languages, whitepaper will encourage more people to join your project.

I did not think that a social network, BRC20 and privacy could come together in a sentence, as a small spam of the BRC20 could lead to an insane increase in fees. Let alone creating a social network that requires thousands of images and megabytes, and these images are visible to everyone and cannot be modified or deleted, which is very bad for privacy.
You can build something on Sidechain, but I think that the performance of a social network on the blockchain would be poor and very expensive.

You really think people are going to join you if they have no idea about what you are trying to build?
For starters, the BRC20's are destroying the main purpose of the Bitcoin network rather than build it, so I am not sure if you will get any fans who are truly enthusiastic about the Bitcoin network.
