My response is probably predictable, but I think all of the satirical / in jest threads lately were all in good fun, and many of them were quite clever. The staff doesn't have a problem with humor, and frankly, we'd rather see a thread that makes its point through gentle satire, than through personal attack.
The only problem arises when somebody misses the humor, and decides to attack the trade idea. That can lead to an awkward moment when that poster figures out that the idea was a joke, I guess. However, in most instances, the joke has either been labeled as such, or was fairly obvious, so I think any hurt feelings often come from not having read the entire post thoroughly. To some extent, any embarrassment is self-inflicted. We can't essentially censor gentle humor on the off-chance that somebody could be offended.
I do wish people would read the entire thread before responding, sometimes. I was told to "get real" because my trade idea wasn't realistic, despite it being labeled as "tongue in cheek". SShoreFan clearly stated he was simply trying to create a trade involving Antoine, Ray, and Scal, due to all the discussion of each in trade ideas on the blog. The recent "Ray Allen to the Patriots" idea... well, that one should have been self-explanatory, but apparently wasn't. Let's try to think before jumping down somebody's throat, okay?
