I'm not sure if this is a general trend or just me. I'm so busy I don't manage to visit everyone very often, even those I particularly want to visit, and I guess much blog visiting is reciprocal.
Looking at other blogs it seems the ones that get lots of comments (and I'm assuming from that lots more visitors) are those that deal with one or two specific topics that interest a lot of people, or they're either controversial or emotional. My blog doesn't fit into any of those categories being a mish mash of my thoughts, ramblings and stupidity. (No-one else seems to do such stupid things - or is it that you're just not telling?)
I'm not planning on changing. I was just pondering.
