I'd share them now if I were you. If there's one thing I've learned after a decade of writing, it's that you have to write for yourself, no one else.

By publishing "filler" articles (which automatically means you're thinking of your potential audience), you're not doing anyone any favors, especially yourself. You might as well write things that you're proud of so that your body of work speaks for itself — then, when people come back to your account, they can see all your great stuff.

Just my two cents.
