I am a big advocate of blogging to give yourself an advantage in your career, but, as Seth Godin says, you need to have “candor, urgency, timeliness, pithiness, and controversy,” (by way of Global PR Week.) In short, you need to have something to say that will interest other people.
I believe that each person has interesting things to say, you just need to learn how to say them, which takes practice. This applies to both blog entries and job interview questions.
Take, for example, the most ubiquitous question: “So, tell me about yourself.” To answer that question well you have to be a good storyteller. You have to sift through all the information you have to find the pieces of information that are interesting to your audience. The same is true for a blog. You need to learn how to be interesting. But you have to do it more regularly than you interview.
If you’re looking for encouragement, Claire Adler writes in the London Guardian, about people who have “typed their way to the top.” Adler shows wide range of routes to blogging success, (and, BTW, she quotes the Brazen Careerist blog, hooray.)
On the other hand, The Flack gives a summary of the people who should not be blogging. Tucked inside that summary is a link to a New York Times article quoting Nick Denton, the man who made millions from blogging, saying for the millionth time that we are in a blogging bubble. Every time he says that I am encouraged because if there’s a blogging bubble then there’s still money to be made before it pops.
