I have had a couple of blogs which I started as a record of my thoughts and experiences in weight loss at first, then cycling, and now triathlon training. Sometimes when someone would ask me about something I had already blogged about, I would just point them to the blog. Eventually, people started reading it. It's not important to me that people read it because it's mainly for my me, but it's nice to get comments once in awhile. I would imagine that to most people, my blog is just a boring commentary about my training (my family says so, lol), but I guess if you're in a similar situation, it's nice to see someone's else's experiences. I enjoy reading people's blogs and keep up with a number of them.
