I think people underestimate the learning aspect. As a blogger, you don't have all the answers, but you'll find out about many of them thanks to the conversation that will ensue. It helps you learn and grow. I always find this aspect of blogging to be freeing and enticing.
If you can stand the snarky answers that a crowd will always generate, there is nothing in the world like writing a blog which basically says "I don't understand this! Please help" and having folks come by and offer assistance.
