When I joined my first online community 8 years ago, I was excited to see and take part in key discussions in my industry. The association I belonged to had launched a private online community for members earlier in the year and I couldn't wait to get involved. But when I logged in, I thought there was something wrong with my browser. Every group and discussion area was a ghost town. Even the questions that I now know were seed questions from the organization didn't have any responses.
