Netiquette
Rule 1: Remember the Human
Those are real people out there. Ask yourself, "Would I
say this to the person's face?" If the answer is no, rewrite
and reread.
Rule 2: Adhere to the same standards of behavior online
that you follow in real life
Be ethical. Don't believe anyone who says, "The only
ethics out there are what you can get away with." But if you
encounter an ethical dilemma in cyberspace, consult the code you
follow in real life. Chances are good you'll find the answer.
Rule 3: Know where you are in cyberspace
Netiquette varies from domain to domain. When you enter a
domain of cyberspace that's new to you, take a look around. Spend
a while listening to the chat or reading the archives. Get a
sense of how the people who are already there act. Then go ahead
and participate.
Rule 4: Respect other people's time and bandwidth
You are not the center of cyberspace. Don't expect instant
responses to all your questions, and don't assume that all
readers will agree with -- or care about -- your passionate
arguments. Before you copy people on your messages, ask yourself
whether they really need to know.
Rule 5: Make yourself look good online
If you're spending a lot of time on the net and you're shaky
in spelling and grammar, it's worth brushing up on them. Know
what you're talking about and make sense. Finally, be pleasant
and polite.
Rule 6: Share expert knowledge
Sharing your knowledge is fun. It's a long-time net tradition.
And it makes the world a better place.
Rule 7: Help keep flame wars under control
"Flaming" is what people do when they express a
strongly held opinion without holding back any emotion.
Netiquette forbids the perpetuation of flame wars -- series of
angry letters, most of them from two or three people directed
toward each other, which can dominate the tone and destroy the
camaraderie of a discussion group.
Rule 8: Respect other people's privacy
Of course, you'd never dream of going through your colleagues'
desk drawers. So naturally you wouldn't read their email either.
Rule 9: Don't abuse your power
Knowing more than others, or having more power than they do,
does not give you the right to take advantage of them.
Rule 10: Be forgiving of other people's mistakes
When someone makes a mistake -- whether it's a spelling error
or a spelling flame, a stupid question or an unnecessarily long
answer -- be kind about it. If it's a minor error, you may not
need to say anything. If you do decide to inform someone of a
mistake, point it out politely, and preferably by private email
rather than in public. Give people the benefit of the doubt;
assume they just don't know any better.
