What are your TOP 3 BIGGEST ONLINE PET PEEVES?

[RoseyReps]

I have a lot of pet peeves that stem from the internet and how people behave. I guess the top three would be:
1.) Short hand - it's fine for texting I guess, but I don't want to have decipher what people are saying
2.) People who forget/deliberately decide to act rude because they aren't talking face to face with someone.
3.) Odd use of capitalization - there is a time and place for capitalization and people tend to overuse it.

I was going to write my normal lengthy response, but honestly I couldn't have said it better than this. The only thing I would add to it, because limiting my pet peeves of the internet to three is just inconceivable, is writing format.

Paragraph breaks, bullet points, etc are your friend and mine. Reading a wall of text is not only irritating, but painful.
