First of all: hello everyone, I'm new here though not really new to the hobby :) .
Now, this is an interesting sub-topic. I'd say there are more than two categories (glue and non-glue builders ;) ) . The important factor, in my opinion, is WHY or WHEN you glue your model. If you do it because otherwise it would not stand on it's own, then your model is in totally different league than others. I'm not saying it's worse (or better), just that it should not be compared with non-glue MOCs because it's not fair. On the other hand, I'm building a big AT-AT as well and it does stand on its own (even though it contains various mechanisms and weighs some 7 kg) but I will not hesitate to use glue before I take it to an exhibition. Our events sometimes last a month or two and I'm not going to take such risk, when all it takes to topple such a fragile model is one decent kick on table's leg...
Anyway, LiLmeFromDaFuture, don't worry about your model being frowned upon - it's just different, not inferior.
Master builders glue models they create for Legolands (not to mention putting steel frames inside). Set designers glue models before they present them to assessment commitees. It is all a matter of purpose.
