Hello there! Let's talk about etiquette in web, or netiquette. As everywhere, in internet you should follow the rules. Here's a list of rules, which I consider important:
1)If you wouldn't say it to someone's face, don't say it online;
2)Respect people's privacy;
3)Remember that real people take priority;
4)Don't abuse your power;
5)Forgive for mistakes;
6)Don't be rude or abusive;
7)Be as brief as possible;
8)Put your best foot forward;
9)Be authentic;
10)Don't be an egomaniac.
