I found this back in 2009, maybe 2010, when I was still "on the inside" and shared it around internally. Some people got a real kick out of it.
Now consider this: every single employee has a corp account, and I would think nearly every employee has a personal account, too. That means problems stemming from being in the right account have probably popped up in every single person's face for years now.
It didn't help when they changed from having the u@h up to just a name. Great. I know my name. I need to know which account I'm in.
Sorry.
