Hi Mary! Glad to meet you (electronically, anyway.) :) My name is Jenn and I manage the social media and community efforts for Telligent. I’m fascinated with the innovation possibilities in your community considering the topic matter. I’m going to see if I can sift through the old bookmark list and see if I can find a post or article that would specifically address your issue. But, just off the top of my head, I think you have to look at your on-domain community and your social networks as different channels that provide different content. Like how a company like Fox, has a broadcast channel, a cable news channel, a sports channel and a movie channel – each channel provides specific content, but they all still carry the Fox brand. This is what you want to achieve with your Linkedin group, Facebook page, Twitter feed and on-domain community. If you are trying to pull some members from your LinkedIn group into your on-domain community, consider pulling in a select topic, but give it a spin that will only be found in the community. As you work on your strategy, ask yourself, “What is the goal of each channel and who is the audience?” Is that helpful?
