7 Internet Etiquette Tips
5. If you get a comment or a like, respond.
People can find out when you are ignoring them online. When you reply to a comment or a tweet that came after the one posted by your friend and do not respond to the previous one, people will notice, It is just plain rude and can cause problems between people. So take time to respond to everyone. It is definitely not easy, but something that has to be done.
6. There is a reason they are called private parts
So do not take pictures of your private parts and put them up on the public domain for everyone to see and comment. Keep your privates private.
7. Do not make plans on Facebook walls
Facebook has messaging and chat screens to make plans and trade numbers and locations. It is not only annoying to your other friends , but can also turn out to be pretty dangerous, especially if you plan on a night out with just your girlfriend or let know that you are alone in the house and would like to throw a party.
