I agree (I think we all do) that it was interesting.
However, I think it was a huge headache for the mods. They (someone) has to try to "police" that, someone could easily put up someone else's real cards as a joke or some kind of revenge thing and the mods would have to be sure nothing usable was showing. And that (as many will verify) was a very long thread.
I also think it was a great trigger for many people to develop the "app itch" and I mean severely. Many people here need to avoid that as much as possible anyway, the last thing they need is "credit porn" to kick off an app spree.
Seriously? "Credit Porn"? Now that's epic! hahaha
