Everyone is talking about the "Blogger Code of Conduct" that is making the rounds.  Personally I think it's a bunch of bull.  If you have a blog, then that is your space.  You have the right to allow or disallow whatever activity you want.  With that in mind, I'd like to remind everyone that I do have a comment policy of my own.  Even though it may seem harsh, I wouldn't worry too much about it.  I've yet to receive a comment which I felt needed to be deleted (with the exception of spam), and I hope it stays that way.
