> Appendix A: Table of disconnected community exchange solutions
The following table shows a selected list of community exchange initiatives. It indicates how a culture of competitive innovation has produced a great diversity of very similar, incompatible and under-used software which restricts users by keeping them in silos.
In this table: FLOSS stands for Free Libre Open Source Software indicating user communities that adapt the software under copyleft licenses; API means that developers have invested time in the possibility of compatibility; Units indicates whether there is a unit of account on the system, as opposed to direct gifting or barter exchange; if a project has an app that might mean it is well resourced or thinking about adoption of young people.
