Well, in a word, YES.
The other factor is that they do not understand that until they 'post', no one can see what they have written.
They believe they must 'sneak' in, type as fast as possible, and 'sneak' out. It is some kind of game to them, and just being able to 'post' gets them some kind of meritorious service award over on DU.
Never tell them that they could spend all day working on their 'post' in a variety of word processing softwares without even being on FR. They might have to then forgo the MSA's.
P.S. Over on DU they think that HTML is a Texas Hockey League.
