It varies by age group, the social-acceptability/maturity of it. I turn 50 next week. To people of my generation, it's EASILY viewed as childish, immature, and petty to post something like that, I think.
To my daughters' generation (20-25), completely not so.
People 25-49?? Probably somewhere in the middle.
Lawyers of all ages and stripes will equally hate the idea, I'm pretty sure.
