Text message and Linkedin are two of my favorite things for business. Linkedin is a very professional social media network. It allows you to connect with people on a professional basis. It is specifically designed to help you connect with people to further your career. My favorite part about it is there is no room for personal drama which is a relief from the other social media networks.
Text messages as far as marketing is concerned is great. I think it is one of the most effective ways to advertise. As long as you share good content and dont over do it you will have a faithful following.
We used an awesome text message/social media service for ice cloud on saturday and it was really effective. It was great advertizing and most of the people that came showed us a text they had gotten from the dealio.
