I'm surprised by the comments referring to this as a troll post. I even searched threads started by the same user, and found nothing particularly troll-like. Of course I didn't read through them all, but at least the thread titles seem like legitimate questions that one might pose to a group of knowledgeable cyclists. What's the beef?
Walking up a hill is something that shouldn't happen very often. If it does then you're gearing needs to change, or perhaps you need to get just a little stronger. I'll admit that even in the lowest gear, I had to push my loaded Trek 720 up a few really steep grades. Most of the time that's what the granny gear is for, but a couple times I just couldn't ride it up. But those were extreme circumstances.
As someone pointed out, walking your bike up a steep hill is not the "Walk of Shame". That's having to walk your bike with a flat tire because you can't change a roadside flat.
