@Reality Forgotten: You answered the question in the way you saw fit, however an important part of communication is empathy with the person or people you're trying to communicate with. So, while Greenlig may have been 'incorrect' in his use of the word angsty, pulling him up on it and implying that it was accidental misuse of words that cause people to start flamewars, was quite obviously not going to endear you to anyone in this thread.
As for the correct and incorrect use of a word, you sound like someone who believes they have a good grasp of the use of language, thus I assume that you also understand that languages are living things that change daily with use. That the English language of now is very different from the English language of even just 100 years ago. That the meaning of words change, and that if enough people know what you mean when you use a word, then that word is seen to have that meaning. For example "W00t" - a word that didn't exist say more than 20 years ago, but now resides in your Location entry. I know what w00t means, you know what w00t means, many other people know too - thus it is a word known to the English language, and I wouldn't be surprised if it entered the dictionary a decade from now.
Words change, and as long as the meaning is understood by your audience, then your aim has been achieved. As such, Greenlig's use of 'angsty' to describe the increasingly aggrivated and knee-jerk reactions of these boards to seemingly quite innocent posts was perfectly valid, as I'm sure the majority of people who read it understood exactly what he meant.
Which was probably; that people should stop jumping down each other's throats for the slightest thing. I'm looking at you, Reality Forgotten. In a metaphorical sense, of course.
@DLS: Nice little house. May I ask how many polygons it has? Something like that would be quite nice for an RTS or something similar - it'd do well seen in great numbers from a distance.
