My social networking pet-peeves:

1. Anonymous, passive-aggressive posts.

“I wish someone would learn how to mind her business” (sometimes there is a “you know who you are” inserted). If you want to call someone out, use their name. If you are talking about a general subject then leave the personal pronouns out of it.

2. Misuse of the LOL phrase.

Using the phrase LOL after something does not necessarily make it funny or nice. I can’t just say, “Johnny is a selfish jerk, LOL” unless there is some inside joke or personal anecdote to which it refers.

3. A distinct online personality.

People who are witty, sarcastic, extroverted, and bold online but are dull, quiet, and passive in real-life exhibit tendencies of multiple personality disorder. Be who you are in real-life online (and vice-versa). Don’t say something on the internet you wouldn’t say to someone’s face. Sometimes I’ll catch people tweeting something in the moment that they are too afraid to say aloud. Live in reality and use social networking for what it is. Do not use social networks as a venue for your alternate personality or to substitute for reality.

Do you have any social networking pet-peeves that you want to add to this list?
