I agree. I must confess that I have lots of students who blog regularly, and though I'm quite interested in their lives, I'm not very interested in what they think about everything that happens in their lives. I just don't have time. What does attract me to the handful of blogspots I follow is a combination of three things: they're people I know and care about, they're people who have a unique outlook or perspective on things, and they're very effective writers. Without all three things, I choose not to invest my time in other people's blogs. That doesn't mean they're worthless or boring; it simply means I have other places in which to invest my time. I'm certain you have people in your life who care about you and are interested in what you have to say. My best advice is to make it as interesting and relevant and effectively written as you're able, and that will get easier over time.
I think personal blogs are only interesting to people who are intimately connected to the writer. One of the benefits of the blogging world is similar to social networking sites - it allows for keeping in touch with many people at the same time. Family and friends who do not see you every day but care about you are the most likely to keep up with your blog.
The internet has billions of web sites and enough information under which anyone would get buried. Unless your blog is really interesting or provides information that serves any other purpose for anyone, it is difficult to expect people to visit it.
This doesn't mean that you are life is boring, it just means that your blog is not interesting enough. Start by telling your friends about it. They would surely like to see your blog. And try to add something to your blog that sets it apart from all the others and makes it worthwhile for anyone to spend their time visiting it.
