“Some of the most popular blogs are maintained by professionals sharing their takes on particular industries. Journalist Jim Romenesko’s clearinghouse for media gossip (www.medianews.org) showed how a personal blog could go pro when the Poynter Institute hired him last year to blog full time. Digital designer Bill Keaggy, 30, maintains two Web logs that he started as internal resources for his employer, a St. Louis design firm. His commentary on visual thinking at www.xplane.com/xblog draws hundreds of visitors daily; others subscribe via e-mail.”
