I think the #MarchOffTwitter is a great idea with one big caveat... Bird app is a diverse space with so many people of many different interests.
In order for this mass exodus to be successful, bitcoiners will have to spread their wings and start discussing and making content about the stuff other than bitcoin that they are passionate about. Otherwise, this place will get real boring if everyone only talks bitcoin all the time!
What are your passions or hobbies that you can bring to the table?
Cheers
