I have mentioned one good use- shoelaces. It makes good tent cordage, although I am going to braided mason's line (in bright colors) for that application.

The trouble with paracord is that it is just strong enough that some people will attempt to use for rappelling or some similar life support application, which is a good way to die. Years ago, the AAC, in one of their yearly Accidents In American Mountaineering reports, commented that pcord had no legitimate application in climbing (other than shoelaces and tent cordage, presumably). Despite that, you will see internet discussions about rappelling on pcord.
