Acknowledge and appreciate your readers especially regular readers by replying to comments and visiting their work.
Add your personality - If you are writing on a particular topic, there are a number of people who will be writing on the same topic. So you need to add that specialty to your blog to make it look different and to allow your readers to take away something that the others are not offering.
People come to your blog out of choice and not any compulsion. If you remember this, the rest is not important enough.
