My love/hate relationship with blogs

I am a journalist by nature, in that I write in my journal on a regular, nearly daily basis. I'm not a media journalist. But blogging has always had that big brother, voyeuristic feel to me. I'm not sure I really want to share my every intimate thought with everyone in cyberspace. And yet, as a published author, whose first book was a grief memoir, that's exactly what I did. I shared my intimate thoughts and feelings with anyone who would purchase my book. So I walk that fine line of wanting to maintain some privacy, and yet, in order to boost book sales and to push my work, I must publicize my actions and thoughts. I am slowly finding my filter.
