Its been a while since rel="author" and rel="me" tags are in talks around SEO related sites and people. With the buzz I also couldn't resist it for too long and I just added them in my sites, just around 2 weeks ago. And, here you go it's working now, if my website appears on google search, it shows my author photo too. How cool is that? And it was so exciting for me to see that. After this it has already improved my visitor count.
