Anonymity for Me But Not For Thee
The AZ Republic, which still prints a couple of unsigned editorials in the paper every day, has decided that it does not like having anonymous comments. Their solution is to have all commenters use their Facebook id. Because it is so much harder to create a fake Facebook persona than it is to put a fake name on your comment.
Postscript- Apparently "anonymous gutter talk" triggered the change. The decision to tie into Facebook was a natural, I guess, because everyone knows the level of discourse is so high there.
