This is a minor rant. Not directed at anyone at blog-city.
If you receive a private email, it is good manners to respond privately. Not to post it on the net and lambast the person who wrote it. If you must lambast them, do it privately.
If someone posts about you in a blog or posts on your blog, feel free to respond in the comments or on your blog. (Although avoiding too much vulgarity is always good for this Miss Manners.)
I try never to diss anyone in my blogs. If I want to diss them, I'll tell them to their face or in an email. (Well, some politicians excepted.)
I was on a “support board” where the moderator posted a message which had been sent to him privately. Then someone got on and said, “Couldn't we do this in private?” Well, it was in private, till the moderator posted it. Poor manners. It was rude to the person who sent it (not me) and to the people who had to read it (since it wasn't addressed to them). I'm not on that support board anymore.
It's the net. It's available across the whole world. That doesn't mean we should be rude.
