Twitter? Depends on your focus, I think. Dev Twitter is pretty nice for me.
Dev.to is great blogging and community platform. Twitter is also good.
How about without social media or platforms in general?
Good question, personal website with a regular blog maybe?
Agreed you’ll basically own your content and In that process you’ll learn how to put your content to the right audience and you’ll learn about marketing. It’s hard at first but i found having my own blog more rewarding
