Things that annoy me:
The improper use of "beg the question" to mean "raise the question".
The improper use of "loathe" when "loath" is needed.
The use of "grow" as a transitive verb, as in "grow the economy".
The use of "at this point in time" or "at this juncture" instead of "now".
You must be annoyed a lot because, from what I've seen, the errors you describe are more subtle than the ones I'm seeing all the time:
"I need some advise."
"I am having trouble peddling my bicycle"
"The breaks on my car aren't working"
"The reason I do that is because it's a good idea."
"Your not doing it right"
"Me and Bob are going fishing"
One of the headlines on our local paper is:
"Teachers Slashed" instead of "Teachers Jobs Slashed."
Sign at store: "Hel-lo" (no reason for the hypen.
Sign for Cafe: "CAEE"
Sign at trailer park: "WINTER PARK" with the "N" backwards.
"Pundents (instead of pundits)"
"Spring is literally around the corner"
