I think that the description above is somewhat accurate. I would also say that people who write in Caps are insecure about their writing and spelling and perhaps think that by writing in caps it will help conceal their mistakes. I personally find it rude, aggressive and a little ignorant on the part of the writer who writes in CAPS. It may convey that the person who is writing is very irritated and since he can’t literally shout, he writes all in CAPS. An illustrious, well educated person hardly ever writes all in caps. There is just something about writing in CAPS that an English or language teacher knows is not right. There is more to the definition above.
