If we created a high-level feature list of our site, we would see users can login, create recipes, provide comments, add items to their library, and well, that's about it. We can do so much more for our users and with our users than we are currently doing. If we want a truly social site, we need to interact with our users and let them interact with each other.
To that end, your challenge is to engage your users to participate in the BrewHow community using one or more of the following ideas.
Obviously, if we're going to socialize BrewHow, we need to add support for existing social media. This includes support for social sites such as Facebook, Twitter, and Google+. Leveraging these social platforms, we can inform users of activity on our site and let them inform others of their activity.
