Recognition. In this business, identification is everything. I cross paths with many authors and writers in the blogosphere. Maybe I haven't met them face to face, but I *know* them by their blogs, comments, and pictures.
Create a brand. Make it your own. For me, it is colors and my avatar. On my blog, Spirit Called, I use burnt orange. Not many blogs have this.
My avatar or icon is unique. Created by my brother, it is a photoshopped picture of me as a one year old.
An author headshot is great. A must in this business. But create something out of the norm as well so folks know you instantly.
Feedback. Comments on my blogs are sent to my email inbox so I can respond to questions or posts. Do you want a personal response in answer to a question? A private critique?
On your profile, enable your email so you can be contacted.
I realize that privacy is king. But if you want to be an established author, you must have name recognition. To do this, people must be able to contact you. Get a Gmail account rather than a personal one if you want.
But create a contact point.
