The Oatmeal
Here's a sampling of the things on this site that happen to perfectly fit my linguistic pet peeve tag:
10 words you need to stop misspelling (I would add the word "misspelling" to this list, though the comic itself got it right.)
Flesh vs Flush
When to use "i.e." in a sentence
How to use an apostrophe
How to use a semicolon (I personally get around this one simply by never, ever using a semicolon.)
The 3 most common uses of irony (It's funny [possibly even ironic?] because the moral of this long-winded debate about what irony is and is not is "don't debate about what irony is and is not.")
What it means when you say "literally" ( reference)
Beyond those, there are a lot of other things as well.
