FYI: OP is talking about a different kind of line than code

Yes, this is exactly what I've been trying lately.

I'm currently working on a Twitter/Reddit clone to test out CQRS and Event Sourcing.

My focus is on making it in a way that moves from a small MVP (make a post) to a full scale clone, in a very "agile" way, e.g. the skateboard > bike > car idea.

BTW, if you want to collaborate on a project, feel free to send me a message 😁
