When people bitch about or give praise to a thread itself, like it's a seperate entity. It's especially bad when more than half of the thread contains commentary on itself. Like here:

The internet did show me how to wrap a present today though, i've got to give it that.
When people edit something and then go out of their way to tag what their edit contained.
EDIT: FIXED SPELLING MISTAKES AND GRAMMAR.
