Not all blogs are written by experts on the subject, in fact most probably aren't. And many blog readers enjoy following a blogger who is truly developing along the way, growing and learning together along the educational path to photography excellence.
When your skills have grown to a certain point you may also want to look into opportunities to write for other photography blogs.

Writing your own blog will allow you the luxury to work on the skills that you want to achieve, while writing for others will push you forward in directions you may not have otherwise gone. Because if you're being paid for your blogging it is going to have to be quality writing in order to be accepted for content for their blog. Writing for other's blogs can be challenging, but it is a wonderful growth opportunity if you're willing to put in the effort.
