So its not the only open source .NET CMS!
It does not run on an open source stack so does not seem to have any particular appeal for people who particularly want to use open source.
It might be free to use but Windows hosting tends to be expensive so it is not likely to appeal to people who want free of cost.
It only seems to be more than just another CMS if you particularly want a dot net CMS: even if you want to run Windows and IIS you can still run PHP and Python based CMS's - you have to want dot net in particular.
