I wouldn't. Let's get more specific.
How about taking advice on social media best practices -- for something serious with high stakes, like looking for a job, becoming visible to recruiters, re-entering the job market after a hiatus or otherwise attempting a career change -- from an advisor whose Twitter account is empty?
Existent in name only.
How about if it's April 2013?
How about if it's the same month that the Wall Street Journal declared The New Resume: It's 140 Characters and @WSJCareers held a Twitter chat about using social media to get a job, concluding it's all about LinkedIn & Twitter & a digital footprint that shows your best stuff.
How about expecting to get guidance on the latest advances in online career development at an event conducted by someone who thinks LinkedIn is exclusively for connecting with people you already know well rather than people you are loosely associated with professionally and want to grow closer to? Someone whose policy lets connection requests go unanswered while, creepily, LinkedIn alerts us she's reviewed our info-rich profile and decided that's a no.
Again, I wouldn't. Yet these are things I have witnessed and experienced recently.
Do you see where I'm going? This is not helpful. This is place holding.
Old-school is occupying the space where actionable help is supposed to go.
And, if you find yourself thinking you don't need up-to-the-minute Twitter advice from a career advisor -- you're wrong.
