If I could only blog about one thing, I would choose books. Books are my passion. And I need an "outlet" for my book energy. When I read a good one, I want to share it with others. Whether 1,000 people read a review or just 1, I can send my thoughts "out there," and expend some of that energy.
But sometimes there are other things I want to share - links, pictures, etc.
If I only blog about books, where do I put those other things?
Why do I blog at all? Could Facebook or some other medium meet my needs better?
