You'd think that DC would have researched the popularity of Clark / Diana before committing to this relationship.
Somehow I doubt it. A quick tag search on Archive of Our Own shows that there are still only 19 stories for this ship, compared to 44 for Bruce / Diana, 404 for Clark / Lois, 665 for Clark / Bruce and a staggering 5617 for Clark / Lex.
laater - clearly Smallville has a LOT to answer for...
