Right, I think the issue at hand is the pendulum has swung too far the other way. People are going so far out of the way to display that they are not just another corp gig that the message can come off as unprofessional, amateur and even suspect of deceit.
I look at these post as the rock-star and ninja posts that used to have flooding the boards a few years ago. Me personally, if I was going to post an ad, I would post one explaining why we love the technology we use and some highlights about how team members where empowered to do great things. Something along the line of "Jim joined us and built out an entire REST facade in Node", "We like Node because it is event driven", "if you know Node we would love to talk to you". Give people a personal connection with the company and the people they will be involved with, most else comes off as corporate, gimmicky, or worst yet arrogant.
