Here's one that definitely gets to me.
Having old QOTWs vanish off the list.

I know for a fact that an early one about pranks vanished- I assumed it was because some of the pranks contained therein were dangerous or mean. But I'm also pretty sure we've done pet peeves before- and yet it's not there.

Someone's fucking with my head.

I concur
and am convinced that we've had this QOTW before.

THANK GOD!
I distinctly remember ranting about bicyclists and SUVs before, but that old QOTW is gone! I was hoping I hadn't lost my mind...

TRL
You could've ranted about them in the roadrage question.
