Well, I am definitely a culprit of overloading my builds with techniques. If you guys want some examples of this, I will offer these two builds:
1. A Farmer's Life
2. Forest Bridge
In the first one, "A Farmer's Life", the build was meant to be a medieval farm. This concept was obviouly lost as I think that it would be relatively difficult to determine based soley on the build. I added a ton of building techninques into this one, including the roof, fence, stone wall, angled field, waterfalls, and snot rocks. I think that even though each one of these techniques is indeed a great technique, they really don't help and the moc turned into a big platter of techniques, and the idea of the moc was lost. I think that the snot rocks were for sure out of place, they are just so trendy that I thought I would try them out.
The second, "Forest Bridge", was actually meant to be a build to try out and show a bunch of techniques (the fact that I even had a build with that purpose shows how much of a culprit of technique dumping I am). These included the waterfall, grasscaping, trees and the bridge. I am not sure this build is as bad as the last one. While it still did include a lot of technique dumping, I think the build did have a sense of cohesiveness that the farm didn't have.
Overall, I think that based just on my two builds I have cited as an example, it can be seen how techniques put in a build soley to show them off can wreck a build. Like you said, Blue, the Lego community does have a bandwagon, and certain techniques can really get overdone and out of context. In my opinion, especially after reading this discussion, is that the build is more important than the techniques it has in it. Extreme building techniques, though they are really cool, definitely need to be used subltly, with a bigger emphasis on the idea of the build. In other words, the advanced techniques should be used only enough that they don't detract from the idea of the build.
