Good Blogging Etiquette

To have good blogging etiquette, you need to first contain proper spelling/grammar.  You have to spell correctly and punctuate as well.  You need to have some content, information that thrives the discussion, not dwindle it.  You have to have manners, the fact being that you can't insult or talk down to people.  You have to have relevancy, or a proper reason for your post.  And finally, you have to have true facts, preferably sited.
