Google has been supporting / pushing the authorship mark-up for a few months now, where articles can be connected to an "about me" page which is in turn linked to the author's Google Profile, whereby a photograph of the author can make its way to the SERPs and be positioned alongside the usual listing.
My query for the community is: who is using this and what has the experience been with regard to affect on traffic?
I am dithering between the idea that the extra visual weighting has to be positive, and the worry that it might lower the perceived caliber of otherwise professional/academic articles to the grade of blog entries.
