I was doing some tag editing and found the STD tag: http://askubuntu.com/questions/tagged/std

It only has 1 question associated with but the tag can be many things, for example:

STD - Standard Input/Output of data
STD - Suspend To Disk (Hibernation mode)
STD - Sexually Transmitted Disease. But since we are in Linux my best bet is this is not it.

How to know what info to put in this Tag?
