I'm going to release Sider on 12/15/2006. This is going to be a demo of the platform ideas. I want to show that it's not only possible, but also easy to develop new tools to work with information using Sider. It won't be very useful from practical point of view and will feature a single package to store notes in a tree-like structure. There're some things I want to fix before release, as well as restructure wiki documentation a little and create website for Sider.
