I'm still pretty new to the blogosphere. I've only been blogging regularly since last Summer or Fall, but even then it didn't pick up until I did bloghops and got myself involved. I felt like I was writing in a bottle and no one was reading it. When I got more involved that began to change.
Blogging to build a readership so you can make more money feels like such a hollow thing. Blogging, to me, is a way to reach out and connect with people. Sure, maybe someday they'll become your readers, but right now they can be a supportive community. They can offer advice when you need it, and leave comments so you don't feel alone in your endeavors. It's also an exercise in what sells and what doesn't, if you think about it. If a post has no comments, you wonder what you said in it to discourage them (like my last post about publishing being 'hell' must've put everyone on the run, and I don't know why). Publishing is Hell! For everyone involved - be they publishers, editors, or just the lowly writers trying to make it through the front door. It's hard to tell what people are going to like. And it's the same with blogs.
So, marketing aside, why do you blog? Do you do it to reach out to fellow writers, to share what you know, or perhaps to learn a little more yourself? Do you focus on or avoid certain topics to grow your readership?
