Mark Goodacre has begun to answer the question, “Why blog?” He has only given us a “preamble” so far, and he has done a good job piquing my curiosity for what more he has to say. An excerpt:
If someone asks me “Why blog?”, my answer is “Why not?” There is actually a danger in getting too navel-gazing about it. If you want to blog, or think you might want to blog, give it a go. See how it goes. If you enjoy it, great. If others enjoy it, even better. If not, you’ve not lost anything, except perhaps a little time.
