The truth is I access the site from my phone most of the time, sometimes i'm half way through typing up a post and I realize I'm not sure about spelling on something, and if I try to open a new tab when I come back to my first tab, the page refreshes and I lose all my work. So if I don't think to look it up first, it is a hassle to do so in the middle.
I will just stick with it though because it is a funny quirk. I think for story purposes, it developed because no one ever pointed out that she was bad at remembering names, not that she is being intentionally malicious or aloof.
