Because somewhere along the line they actually felt the need to come up with a Ten Commandments of blogging. Yes, really, they did. Everything else was solved and they've moved onto this.
The Blogging Ten Commandments, according to the Evangelical Alliance:
You shall not put your blog before your integrity.
You shall not make an idol of your blog.
You shall not misuse your screen name by using your anonymity to sin.
Remember the Sabbath day by taking one day off a week from your blog.
Honour your fellow-bloggers above yourselves and do not give undue significance to their mistakes.
You shall not murder someone else’s honour, reputation or feelings.
You shall not use the web to commit or permit adultery in your mind.
You shall not steal another person’s content.
You shall not give false testimony against your fellow-blogger.
You shall not covet your neighbour's blog ranking. Be content with your own content.
Well already we broke #8 by publishing this. We also don't need a blog to commit adultery in our minds. Also, Johnny has a big blow up 'YCD Blog' doll he idolizes, oops.
