To play devils advocate, Linkedin is professional profile site. Personally I would not put a photo of myself holding a drink for this reason and agree or not, its reasonable to expect people wont like this. If someone said the same cause they saw a Facebook picture of you holding a beer then I would be in absolute agreement.
On a whim, I recently updated my LinkedIn picture to a photo of myself in a multi-coloured clown wig. This put an immediate end to all messages from recruiters.
They only grep the CVs for words, if you put you're a lion tamer, archeologist, but has the word PHP in your CV (or something similar) you'll get a flood of IT jobs
I once worked for a design agency that was building the website of a major super PAC run by the son of a governor that most people on HN probably despise. I was tasked with turning the designer's PSDs into a Wordpress site and one section was bios of all the officers.
My contact at the client gathered up all the photos and bios and emailed them to me. Maybe 25% of the photos were professional headshots. The majority were just crappy cell phone pictures.
The rest were people at parties holding a beer. I emailed my contact to make sure he wanted me to use these and he told me to go ahead. Sure enough, a day after we went live I get a pissed-off call from him demanding to know why I used those photos.
Where do you draw the line? is it OK for me to have a shaggy beard? How about long hair? Tattoos?
My personality is my personality, and when you hire me you're going to get the whole thing. If you can't handle it, I rather you don't even talk to me in the first place.
I look forward to a future where nobody cares about this stuff.
I also want to work with religious nuts, boring fuckwads, skiing junkies, food fetishists, and closet crocheters, as well as fellow social drinkers; and I want them all to be able to keep their oddities out of the workplace. It doesn't suggest a human amount of social intelligence to have a divisive image on your public profile.
If they don't want my whole personality, they can't have my intelligence.
I refuse to turn myself into a "corporate robot" for the sake of a paycheck.
