Qualified to interpret the Bible?

Dr Jim West is rightly concerned about the proliferation of bad Bible interpretation on the Internet. So he has put forward guidelines on who is qualified to interpret and comment on the biblical text, basically that they should be theologically qualified and actively involved in a Christian or Jewish community. I don't entirely agree with him: many without formal qualifications have deep knowledge of the Bible and are fit to interpret it as long as they are aware of the limitations of their understanding. But, in case anyone wonders or questions my credentials, I do meet his guidelines; my theological background is given in the introductory posting on the blog.
