If I blog will they come?

I keep wondering, if I blog, who would read it, and why? Do I have something important to say? Reflections have always been difficult for me. I'm much better at reacting or commenting. Recently, I was told, "but your public needs you". Just not sure who that public is. When asked a question, I can answer. When I read something that interests me, I'm willing to share. So what am I passionate about in education that I should reflect and share about? Only time will tell.
