Whether your goal is professional or personal (though it's best applied to the former), blogging well builds credibility and creates a readership of devotees. While you may not have "fans" like a rock star, you'll certainly find people from diverse geographic and professional backgrounds that enjoy your writing and have a positive association with you. Outside of blogging, there's very few channels that offer this reward.

Blogs build familiarity and positive branding and if I remember my business school training, the cardinal rule was  - people do business with you because they know you, like you and they trust you - blogging accomplishes all three (and they show off your expertise in a subject).
