How do they know they had feathers? I've seen the skin impressions at the American Museum of Natural History, and see no feathers. I'm not saying they're wrong; I just would like to know.

Just recently they made some discovery that not only indicated the presence of tiny (microscopic) pre-feathers in fossilized dinosaurs, but it could also determine their color, and a lot of them were brightly colored. I can't recall the details or where I heard it. So the thinking now is not that feathers developed to assist in flight, but rather they developed for much the same reason as they exist today, for attracting mates. And as a side-benefit it turned out that as feathers evolved they were pretty useful for gliding and eventually flying to.

I'm going to have to dig that article up. If I find it I'll post it here or PM it to you guys.

Not all dinosaurs had feathers. We have skinn impressions of scaly dinosaurs. However, we also have feather impressions, meaning some dinosaurs had feathers and some didn't.

There's been a lot of feathered dinos showing up in China in the last 15 years; there's a deposit which has lots of fine grained volcanic ash, which preserves soft tissue detail well.

Here's an couple of examples, a Microraptor and a Sinornithosaurus:
