WruDi - What are you doing? is an Open Network Service. Our main goal is to provide a fair and transparent service that preserves users' autonomy.
The software also implements the OpenMicroBlogging protocol, meaning that you can have friends on other microblogging services that can receive your notices.
The goal here is autonomy -- you deserve the right to manage your own on-line presence. If you don't like how WruDi - What are you doing? works, you can take your data and the source code and set up your own server (or move your account to another one).
