Fuelled in large part by the usercentric Web 2.0, the internet has evolved considerably as a communications platform, offering people innovative means for keeping in touch and sharing knowledge instantly with others.

Blogs and wikis, which allow people to broadcast their thoughts to the web and collaborate on documents are the heavyweights of this movement. And though they are wonderful tools for bringing disparate people together and for accumulating knowledge, they can also quickly devolve into the online equivalent of grunting apes. And you don't want to be an unruly ape, do you? Of course not.

As we demonstrated with "The Ten Commandments of cell phone etiquette", new modes of communication require new codes for behaviour. Just keep these Ten Commandments of blogs and wikis in mind as you type, and you will rise above the fray - and help facilitate fruitful, lively discussion.

And if you know of one we missed, feel free to contribute a commandment of your own in the comments box.

1. Thou shall not confuse thy opinion with gospel truth. There is a strong temptation, particularly when discussing contentious issues, to claim unimpeachable authority on the subject at hand. Yes, everybody is entitled to express personal opinions, but by treating your blog or wiki like a panel rather than a pulpit, the dialogue will more likely be divine.

2. Thou shall not invoke personal attacks. One of the magical powers blogs and wikis seem to possess is the capability of turning otherwise sensible people into bickering schoolchildren. Unless the discussion subject is "Say something insulting about somebody who holds a different opinion than you," leave the personal invective out. Rule of thumb: Argue with the post, not the poster.

3. Thou shall stick to the subject at hand. Blogs in particular can get tangential in a hurry. To some, that's part of the charm - you start with an idea and end up somewhere completely different. That's all well and good, but let tangents arise organically within the context of the discussion. If you've got something wildly off topic to say, start a new thread or keep it to yourself until it becomes relevant.
