Is It UST?

This isn't exactly meta, per se, but delves into some meta issues within the context of fanfic and writing. You can apply this to many fandoms, but I will be using SG-1 to illustrate my points.

( So, is it UST? )

I wonder what are your thoughts on this? Again, I used SG-1 as an example but it can be applied to any show, despite whether the show contains canon pairings or not.
