An Internet search for full-time business travelers who write Web logs produces astonishingly low numbers, considering the eight million Americans whom the Pew Internet and American Life Project say publish a blog.

But that appears to be changing. "Just wait," said Steve Broback, a business traveler in Woodinville, Wash., who edits the new blog Inflighthq (www.inflighthq.com) and is an organizer of a blog conference called the Blog Business Summit. "The rush is starting."

Mr. Broback, whose Web journal is sponsored by Connexion, Boeing's wireless division, writes about the plight of the road warrior and offers links to news for business travelers. And he expects a lot of company soon. "In a year or two we'll probably even have blogs focusing on vintage airport vending machines," he predicted.

One business travel blogger noted that after her colleagues began reading her posts about being homeless after Hurricane Katrina, she felt she lost her anonymity. Her quote: "When your boss is reading your blog, you say to yourself, 'Well, maybe I shouldn't be writing about staying at the Ritz-Carlton.'" Another reason business travelers should be wary to blog: competitive intelligence. A blogging specialist in the article noted that business travelers who mention cities they're staying in or about to visit could reveal "enough information for a competitor to surmise what's going on."
