The Blog Herald has an article entitled Problogging, Hype or Reality?, which questions whether blogging is a viable career track.
About two years ago I got some folks excited about creating an industry organization focused on professional blogging, called the Professional Bloggers Association. Even though it never took off, largely due to my need to make a living leaving little time to devote to its development, I felt problogging would eventually become a career track.
I´ve since changed my mind. While some companies, like Stonyfield Farms, hire full-time bloggers, most add blogging to the job description or merely encourage employees to blog, even though they´re not compensated for it. I recall even Scoble mentioning that he didn´t blog on company time. I never believed that, but I recall him saying it at the Blog Business Summit in January 2005.
(BTW, don´t you think it interesting we still refer to Stonyfield as an example of a company hiring someone to blog; perhaps that´s further evidence that problogging really hasn´t taken off.)
I´ve earned my living thanks to blogging since November 2004, but it is hard work. I do hope the landscape changes and we see more companies (Fortune 500s included) bringing on full-time bloggers. For now, most are relegated to part-time income blogging on networks like Weblogs Inc or B5Media, or even worse, trying to earn a few bucks on their own.
