(Text slightly amended as previous text referred to a comment now dated)
Apologies for starting a distracting thread. This blog is unmoderated for very good reason, namely that people have busy jobs. I suggest a couple of rules:
1. No personal insults
2. No direct unsubstantiated accusations
3. Use some sort of unique signature. Not necessarily an identifier. Most of the people who comment here have a clearly identified signature whether anonymous or not. There seems to be disagreement on whether this is necessary. To me it would avoid a lot of potential confusion.
