Yes I've owned ancient 531 frames with the skinniest stays, ridden them really hard and they last forever so I take for granted that steel is eternal.
It seems that when you stray from the well worn path with frame design you're on your own and small design flaws can kill seemingly tough frames whilst the trad framebuilder rule book has learned all this stuff the hard way!
I know what you mean. To stick up a little bit for the GT, I did ride the hell out of it - it went from SS commuter to SS MTB to trials bike to geared MTB to panniered up touring bike to commuter to courier bike. The fact it held on so long under me was probably amazing :D
Fair enough - my 90's steel rigid mtb was used in the superG nationals, XC racing, club runs, touring, commuting and riding vert in the park - I even moved house on it once
