Why don't more people blog?

It is a familiar refrain in the blogosphere that "blogging is not for everyone" -- some people are not motivated, disciplined, or interesting enough to maintain a blog, they say.

I don't buy it.

Every person has interests; a blog is just a medium through which people can express those interests. And I believe that once people experience the benefits of blogging, passion will replace the need for discipline. The real problem is maintaining the discipline to get through those first few months when no one is reading. (It helps if you have a few close friends to read and comment while you are getting started; otherwise, it could get pretty lonely.)

And I don't buy the time excuse. Blogging needn't take more than 30 minutes a week; you do not need to post nearly as often as I do to see benefits.

I have yet to hear a good excuse for not blogging. Please let me know if you find one.
