Every people puts its own scent on its food, and it accepts change only if it can conceal the change from itself, by smothering each novelty in its scent. Optimism about change, whether in politics, economics or culture, is only possible if this premise is accepted.
A blog is definitely something you put your "scent" on. So could could we infer that corporate blogging could be a vector for change, not only for the organization but also for the author of the blog? I definitely believe so.
Shoot. I already quoted this last year! Well, never mind.
