It is a long and involved story, but essentially a number of users didn't like how Crimson (who acted as admin of thentsh, while I just wrote the code) was running the site. He owned the domain and name and provided hosting while I had everything else so I secured new hosting and a new domain independent of Crimson.
The site is essentially the same - all of the conversations, notes, users, etc from theNTSH have been imported over. Crimson has nothing to do with the running of socialnotoworking.nu
