Strangly enough, my Twitter account is pretty anonymous. Just a logo and not even my real name.

Many accounts I follow with 10K+ followers also enjoy a high level of anonymity.

My advice would be to just start anonymously and rebrand later down the road if you feel like getting your actual name and face out there.

Even Stephen King published under a pen name.

If it's good enough for him, it's good enough for me.
