Google defines netiquette as, "the correct or acceptable way of communicating on the Internet."
This video pretty much sums it up:
- It is hard to tell how how something you put on the internet will be interpreted, so before you post, think about what you're saying and the manner in which you say it. Would you really yell at someone for spelling something wrong? If not, you probably should not post your grammar correction in all caps.
- He may be joking about the silly mirror pictures with your cell phone, but it is important to think about the sorts of pictures you post online. Before you post that drunken picture of you in your underwear, dancing on a bar, you may want to think about who could be seeing it. You wouldn't want one fun night out to cost you a job or put your character in question in an important situation.
- He talks about treating tech support as humans. I think it is important to remember this not only when talking to tech support, but in general on the internet. Sometimes it is hard to think of the abstract internet people as real human beings, but it is important to remember that on the other end of that little box is another person like you, with real feelings which you could be hurting.
