To a great community manager, you have to love people first and foremost!
You have to love their complexities, their wonders and all that they have to give. Being a great community manager means that you are driven by finding what drives others and then mobilize them to action. You have to understand that community is a family - it's a collection of people that you don't always get along or agree with but it's because of those differences that the community is stronger and can achieve more. Lead by participation, share knowledge and empower your members. Create a feeling of belonging in the community and recognize the opportunities to create bonding. BE ORGANIZED! streamline your tools and maximize your efficiency so that you have more energy to invest in your community. Communication is key - I use Mobilize because it combines about 10 tools in one and makes my life so much easier.
