I second what mcgraw says. I would also add: If you have a topic that you love talking about, then go ahead with the blog. You will need to have a regular posting schedule. Try getting a few posts in draft mode (ready to be published). This way you will have something to post even if you do not have the time to post at that interval (weekly, biweekly etc.) Letting your readers get used to a regular posting schedule will help a lot. Twitter/Facebook are good tools you can use to make people aware of your blog. If you have something interesting to say, people will follow you :) Good luck!
