Do you consider your readers choices or your choices when you write a new blog post?

A good and prudent writer establishes his/her own specific audience before he/she decides to write. And that is the rule!  

Good writers should have a mix of both, that's what extends the life of your following.

Personally, I prefer on writing about topic of my own choosing.

Mostly I write on that topics on which I have a command and have sufficient information and knowledge. On the other hand, I take care of the trends and look for the topics or information that readers want to read. Here is my blog: genuineonlineearnings.blogspot.com
