Tone of Voice
Since common computers can't portray the inflection or tone in a person's voice, how articles are worded can directly affect the response to them. If you say
Anybody using a Vic-20 should go buy themselves a life.
you'll definitely get some responses—-telling you to take a leap. Rather than be inflammatory, phrase your articles in a way that rationally expresses your opinion, like
What're the practical uses of a Vic-20 these days?
which presents yourself as a much more level-headed individual.
Also, what case (upper or lower) you use can indicate how you're trying to speak—-netiquette dictates that if you USE ALL CAPITAL LETTERS, people will think you're "shouting." Write as you would in a normal letter to a friend, following traditional rules of English (or whatever language you happen to speak).
Computer Religion
No matter what kind of computer a person is using, theirs is always the best and most efficient of them all. Posting articles asking questions like What computer should I buy? An Atari ST or an Amiga? will lead only to fervent arguments over the merits and drawbacks of each brand. Don't even ask The Net—-go to a local user group, or do some research of your own like reading some magazine reviews. Trying to say one computer is somehow better than another is a moot point.
