Stupid Questions, 2nd half of December

The most re­cent post in De­cem­ber’s Stupid Ques­tions ar­ti­cle is from the 11th.

I sup­pose as the ar­ti­cle’s been pushed fur­ther down the list of new ar­ti­cles, it’s had less ex­po­sure, so here’s an­other one for the rest of De­cem­ber.

Plus I have a few ques­tions, so I’ll get it kicked off.

It was said in the last one, and it’s good ad­vice, I think:

This thread is for ask­ing any ques­tions that might seem ob­vi­ous, tan­gen­tial, silly or what-have-you. Don’t be shy, ev­ery­one has holes in their knowl­edge, though the fewer and the smaller we can make them, the bet­ter.

Please be re­spect­ful of other peo­ple’s ad­mit­ting ig­no­rance and don’t mock them for it, as they’re do­ing a no­ble thing.
