The service that I had signed up for was Formulists because it sounded interesting. Basically, the service helps you get your messages/tweets out to a specific group on twitter. It helps us find and analyse groups of people on Facebook. To help people understand how to use the site, they have these demos that we can view to show us what the site does. Each page throughout the demo has a help button that we can click on for more details. There is also a video to help us understand formulytics. Overall this site was very useful and can help many advertise their products or whatever that they choose. It can help people gain information as to how each group reacts to certain things.
