What a Person Puts in a Blog

So what is it exactly that a person puts in a blog??  I'm not totally sure and was hesitant to start this blog thing, jumping on the bandwagon...but I'm in now. What do I plan to put in a blog?? My life's news?? My thoughts and feelings?? I haven't yet decided. I'm open to suggestions but I'm hoping to somehow get a feel for all this. Did anybody else do it that way?? I'm so certain I'm not the only one who didn't know exactly what to talk about in the beginning. The important thing for YOU to know is that I can't write books, I can't sing songs, and my intellect is no kind of impressing. I just want to share. That's my plan for this blog. We'll see how it goes.
