A partner of ours, Uusi Suomi, has been running a Wordpress MU (now called Wordpress MS) -based blogging community since 2008. The basic stuff – blogging – has worked relatively well there all the time. The use of the word “relative” instead of “great” is based on the fact that the platform was never the most up-to-date version of WPMU and much of the cool stuff that is available now was not there for Uusi Suomi.
