Using social just to pimp a business is obnoxious, and given what your business is, frankly it shows you are precisely unaware of how this stuff best works.
I’m not talking about the consultants who are online and post to social media. That’s fine. I mean the people whose every post is a link to their blog, or Fan Page, or QR code, or whatever else they read they should do in last month’s Wired Magazine.
I have many friends on GP, Twitter, Facebook, etc. who do not go out of their way to post links to their businesses. Instead they share interesting, unique posts that demonstrate their expertise. This does work, as it gets people to seek them out to hire them.
Please follow their example. Smearing the walls of a social network with your branding feces doesn’t make anyone want to listen to you, much less hire you, you unintentionally ironic fool.
