A few people commenting here at my weblog have taken to hurling quite offensive personal insults (most of which are directed at people other than me.) I'll will remove those comments and ban commenters who cannot keep things civil.
I've got not problems with healthy debate, and in general don't even mind absorbing personal insults aimed at me, but if the language gets out of hand or people start using my blog to insult other members of the Mozilla community, their access to the comment interface at this weblog won't last.
Also, off-topic comments are subject to removal. I've got lots of posts here and I read most of the comments, even on the older posts. If you can't find the correct post to comment on here at my blog, I suggest you get a blog of your own and use that.
That being said, I think that comments here are overwhelmingly constructive and add a lot of value, and I want to thank all of the people who, by contributing in the comments, have helped make this blog so exciting over the last few years.
