Hitting the 'Next blog' button all day . . . I've taken in a lot of blogs that way, and I notice patterns - recurrent age demographics or recurrent themes or topics or whatever. Sometimes I think I'm too old to have a blog. Sometimes I think I'm too young - I've noticed a ton of retiree 'hittin the road in our RV' type blogs lately. Also, many people try to start businesses off of a blog. A lot of people create a blog just to chronicle one particular trip, or one particular pregnancy or one particular bout with one particular disease.
