Why Blog?

Why blog? For me, it is essentially a mix of personal curiosity and peer pressure. On the one hand I am just plain curious. Will my blog be of interest to anyone? Am I actually capable of blogging well? What might blogging well even look like? How long will I keep up this blog for? And so personal curiosity propels me forward. On the other hand, there is some peer pressure. My friends blog. My colleagues blog. Make no mistake, my kids will blog. Maybe not now, but soon to be sure. And last month a total stranger asked me, "Hey, do you blog?" and then appeared genuinely disappointed when I replied, "Me... blog? ...No". I confess, I still feel somewhat poorly that I let this guy down. So peer pressure is a factor too. That's me, but why do YOU blog?
