I'm going to try a short experiment. Well, I'm going to make some changes may become permanent and some that will be permanent.
The first is to ban the word 'nigger' from comments and trackbacks. This is certainly the most controversial change and the one that will probably most readily be reversed. I do so only in the context, somewhat symbolically, over Michael Fisher's excess some time earlier this Fall.
Fisher himself has been unbanned from commenting on Cobb as has Chance Kelsey, riding on the coattails of goodwill and the opportunity for more debate in this corner of the 'sphere.
Additionally, I will turn off Capcha and try to manually add text filters to get rid of spam. This should encourage more comments by making it slightly easier for folks to say what they want.
