A general profile photo that looks in the camera
After looking at today's issue of Perl Weekly, I remembered of a nice advice by MJD that basically boils down to: make faces look at the content, or at least not look away from it.
My photo loaded on Gravatar was looking towards the right, which is good when your photo is put on the left of the page, but a disaster when it's placed on the right (which is what happens on Perl Weekly and here on blogs.perl.org, by the way).
The fault is totally my own: the general photo that might end up anywhere SHOULD look at the camera, so that it will be at least neutral in the general case! I changed it of course, even though I'm not sure I like the results... time passed!
