Twyt is a BSD licensed Twitter API interface for Python. It provides an interface to the remote Twitter API functions and classes to allow easy manipulation of the returned sets of data, such as status messages and user information.
When it comes to interacting with the over800 social APIs, it's not just about your friend's data. It's also about your own data. The Personal Data Revolution is about making that data available to you, which is where the APIs come in.
What would it mean to have a stripped down social network that was also secure? It would look like Tuenti, the social network out of Spain. To give an example of how seriously they take security, the Tuenti API is closed because "of our efforts to be the most private, secure social network on the market..." But if you play nice, they can make exceptions for commercial apps and games they have tested.
