Well said. I have found it a whole lot easier to focus in on a few things that I am knowledgeable about and have stuff to say. Taking a theme is a powerful way to keep writing on a regular and consistent basis. People get to know you. You get to learn more about your theme. I must say I am a lot wiser on Australian Native orchids and photography after 48 posts so far and about Investing with 92 posts so far.
Jumping around like a jack rabbit from topic to topic is not going to produce that.
@carrinm, excellent!
Whereas I recognize that people all have their own reasons for using social media, O also know many of us (myself included) are ultimately in the business of creating/supporting "Brand Me," whatever that may mean. We built expertise around certain areas or thoughts... what Google likes to call "authority."
