I read your post in the original thread and thought you were being a little harsh. Were you wrong? Not necessarily... if that's how you see it, then that's OK. I think you could've worded it a little differently, but at the same time, if someone is going to post their work on these boards there will occasionally be something said that offends them. I generally go the route of "If you don't have anything nice to say, don't say anything at all".
If you see flaws that you need to point out, by all means do that, but do it with some suggestions to improve their next build. I too, hate seeing a thread where everyone says "awesome" and "great- job" when the model is not done at least passably well, but unless I have some constructive criticism to add I just move on.
Just my two- cents.
