There are any number of reasons to blog about things. Perhaps you want to become famous and well known, perhaps you want to help others, perhaps you just want to unload your knowledge. All of those are valid, and good, reasons to blog. However I have one more: blog for your interview.
Most of us don’t want to be famous, or even well known. Most of us just want to have a successful career and want to be sure we can get a job if you need one. Blog for those reasons.
I could encourage you to write about your career, but not to teach others. Write about your career to show the person that might consider offering you a job what you know. Write your posts that show that you have knowledge and
- can solve a problem
- have knowledge on a topic
As I mention in the talk, If I am interviewing you, or considering it, I don’t care if everyone else in the world knows how to backup a database. I care if *you* know how to do it. Your blogging on the topic, on simple topics, lets me know what you understand and how you solve problems.
This doesn’t mean going through Books Online and re-writing all sections. However it does mean that as you perform tasks, even simple ones, write about them. Tell me why you did something, why you chose those options for backup, what the implications are. This tells me what you know, and what you don’t.
