Do strong opinions matter?

 A few weeks ago I stumbled upon a literary agent's blog who said that writers should not express strong opinions on their blogs because publishers don't like this. There were other recommendations but this one is the one that surprised me. There are readers out there who  disagreed with this agent's recommendation claiming that writers who do not express their opinions are not interesting and can be boring.

   I tend to write posts on which my personal views and opinions are made evident to the public. If I think that a subject is controversial I may take some time to process my ideas and thoughts before I dare write about it. In some cases I avoid writing about some topics altogether fearing that it may not be the right time in my career to do so.
  As writers we already take risks when we craft our own stories. Do we also take risks when we blog?
  Do you tend to gravitate towards blogs that are not opinionated? Or do you prefer blogs that express strong opinions? Do you prefer to sound neutral when you write a blog entry?
 What is your personal approach?
