Since Social Media (or social networking) is about engagement [at least I think it is. You can say otherwise in our Facebook Discussion linked below]. So, you won't really ever get it right unless you do just that.
In the true spirit of using social networking as an effective marketing tool, InterCoastal Net Designs has created a Discussion on the very topic. Please join the convesation on Facebook. Let's us know what you think on the subject. Have you used it? Does it work? Why? Or if you simply have a million questions that need answered…join the crowd.
