Does it make sense to use rel=author on every page?

If you assume that rel=author increases click through rate in SERPs, would it be a good or bad idea to implement it on every page on your site?

I don't see any reason why not to add it to any page that was actually created by a human author.  I'm not sure if it would be appropriate for a automatically generated pages like category or other archive pages for instance.  But with the new way of adding rel=author in the head section of a site, it's much easier to add now than before, and I expect it to be more and more widely used.

I have it added to every page and I do think it helps with CTR.

One concern some have had, however, is that if you ever want to sell your site, then it is branded to you.
