I manage a community that provide our participants with information about how to settle in a new country mainly offline. Outside there are a lot of Facebook groups that are intended to the same purpose even though they are not really efficient. We are wondering if it will be useful to build our brand new website-based Q&A forum and compete to bring in the participants from the Facebook groups to our QA forum. In order to do that, we are evaluating the Pros and Cons. What are the insights that one could think of when building an alternative to an existing, low quality group of discussion?
