I stole these off a blog.
1) Always remember the superiority of the real world over the virtual world.
If you are spending more time interacting with people over the Internet than you do in the real world, then you need to seriously curtail your online activity. God made us physical beings and we cannot replace physical interaction with virtual interaction. It’s just not the same.
2) Your salvation is more important than your involvement on the Internet.
If frequenting a blog or forum disturbs your peace and makes you anxious, uncharitable and/or unkind to those around you, you should simply stop going to that blog or forum. I have had to abandon certain forums and blogs because I found myself too upset with those I encountered there. It is better to simply walk away.
3) Don’t ever say anything on the Internet that you wouldn’t say in person.
This is a pretty common suggestion, but it is very true. If you wouldn’t call someone a putz to their face, don’t call them that online (and if you would call them that to their face, perhaps you need to see your confessor).
4) Don’t write anything in anger.
If you write a post or comment on a blog or on a forum in anger, be sure to preview it before posting. Then delete it.
5) Don’t stereotype people.
It is very easy to stereotype the people we “meet” over the Internet but the truth is that most people don’t fall into nice and neat categories. Remember to just debate actual arguments raised, not positions you assume the person also holds. Don’t think you actually know people you only encounter online. You don’t.
6) Take at least one day off a week from the Internet.
Preferably Sunday. Remember that man was not made for the Internet, but the Internet for man. If you feel you need to be on the Internet every day, then you are showing signs of a dangerous addiction. This is unhealthy, even if the sites you go to are not harmful themselves.
7) Always assume the good intentions of others.
If someone writes something that could possibly be interpreted multiple ways, assume the best interpretation. I have seen countless examples of someone making a point, someone else misinterpreting it and attacking it, then a whole discussion ensues before the original poster returns to say that he never meant what he was accused of saying. Writing is a difficult task, and often what we write isn’t exactly what we mean. Give people the same benefit of the doubt that you want to be given.
I have removed a few rules that aren't appropriate for this site but will also add this one:
8) Remember we all want the same thing.
We are all parents (or parents to be) who only want what's best for our child/children. We do not always agree on what's best but at the end of the day it's no skin off my nose if we can't agree because I can still do whatever I want with my own children.
