Angela Connor points out that, just because you’ve built a lovely new community doesn’t mean that people will change their habits and visit yours over their existing networks:
Your new community, no matter how great will not change habits. What I mean by this is you will not be able to stop potential members from posting on Facebook or twitter or their favorite Ning community. If you are assuming that your new community will become the new gathering place for those belonging to the niche, I think you will be disappointed.
Whatever your community is, whether it’s a brand community or an internal social network, people will only create a new habit around your offering if it consistently gives them something really valuable. Communities take an awful long time to build. Like everything else in social media, there’s just no ‘quick win’.
