Someone asked me these questions via email. And sharing is good. So I thought I'd share the answers:
1. Why do you blog?
The usual reasons: Ego. Because I like sharing stuff (and you discover that if you share stuff you get stuff back.) To practice writing. To practice thinking. Because it's become a habit. To keep a tab on things that I've thought or noticed. To make friends and influence people. To write fewer emails. To show off. To poison the minds of young planners all over the world. To earn upwards of $100 a year in advertising revenue. Because if I didn't I might have to get on with something worthwhile.
2. How has having a blog affected your career?
My career used to be based on my early discovery of the feature that let you put pictures in PowerPoint. Once this became commonplace I had to find a new gimmick. Hello blogging.
3. What kind of relationship do you have with your community? and how do you go about developing it?
I hope that I have the kind of relationship with my community where I wouldn't call it 'my community' and I wouldn't go about 'developing it'. I think of the blog as a place where people visit or hang out. That's about it. I also like that it's a place in a distributed village, there's a whole loose group of people who visit each others blog, chat about stuff, share ideas and are even starting to meet up and talk in real life. I think that's the best 'professional' thing I've ever been involved with.
4. What do you perceive to be the future of blogging in your profession?
Before long the blog will have replaced the resume/CV. Or whatever the next evolution of the blog is. If your job is having public ideas I suspect it'll become very surprising to people that you're not doing something like a blog.
