Grammar ignorance that annoys me

There's a number of grammar ignorance errors that I see on the web that really annoys me. Let me offer some examples:

1. "should of" - OK, what you are saying actually is the contraction of "should have" and that's "should've". You are NOT saying "should of", you are saying "should've".

2. Take and Bring - These verbs are used wrong A LOT. You take medicine, you take things with you, but you bring it when you when someone asks you to bring it. You don't bring back it to the store, you're taking it back to the store. When you're away going somewhere else, other people ask you to bring something with you. While you're doing that, you're taking it with you.

3. Than and Then - 3 Is More Than 1. Then you'd write it 3>1.

4. How to Use Only.

5. Apostrophe S - It's sad when people get this one wrong. Plurals don't need an apostrophe. People even get the possessive "its" confused for the contraction "it's" which means "it is." I really hate seeing plurals that use an apostrophe.
 
6. Using "revital" (which isn't a word) when they mean Rejuvenate or Renew.

7. "Even know" when you mean "Even Though."

8. Your and You're - It's just 2 more characters. Type Them. One means "You are". The other is 2nd person possessive.


The other thing that annoys me, aside from grammar ignorance, is people who don't know where to pull up at a traffic light. There's a white painted bar on the road that shows you where to stop at the red light. You do not stop behind the vehicle detector loop, but instead on top of it at least. But get that front bumper (or even your front tires) on that white bar. And a green light during a left turn (this is known as an unguarded left turn) means progress into the intersection and wait until it's clear. If this means waiting until the light turns red again for traffic to clear, so be it.
