It bothers me that it bothers people when they think someone is incorrectly using 'literally'
adverb
1.in a literal manner or sense, exactly; the driver took it literally when asked to go straight over the roundabout,
2.informal used for emphasis while not being literally true; I have received literally thousands of letters
So literally can literally go both ways.
I hate it that enough people have used the word incorrectly that the word now means both one thing and its literal opposite. The word has become literally meaningless. The annoying habits of English speakers (and posters) have literally ruined a word.
I'd also like to hop onto the signature hate bandwagon. It's a behavior that does nothing but draw attention to itself.
I also hate it when posters parse their posts in weird ways. Example:
Sometimes people post
their thoughts like this so that one thought stretches
across multiple lines
no punctuation
I've seen two posters do this. Not sure if they're posting from phones where that quirk makes it easier for them to read what they've written, or if they're trying to make haiku posting a thing or what, but having to reread posts to figure out where one thought ends and the next begins is annoying.
