I had already heard the PVP comic had done a strip about the pending CoX closure (and has a history of doing CoX strips now and again). I never could get into that comic, but I do read a bunch of others include Wayward Sons and today's space took a break from their wonderful story and art to give us a nod by using a PVP strip.
So I have to admit, the PVP nod is causing traction amongst other online hero comics, since it's a group who tend to cross-promote each other's comics.
I don't know how to specifically link to today's comic (9/18/12), but here's the site link:
