Another thought is to find a way to make scouting more fun...
We do both Pit & Match scouting (although echoing others here, match scouting gets more weight than pit... anyone can say they can score 20 tubes in a match, to see them do it is another).
Our pit scouting was developed by one of our mentors who knows labview really well, and he created this really awesome GUI with the help of our strategy/drive team. In a way, it makes scouting fun

They have a visual way to add tubes to the rack, they can type in notes on teams, and indicate extra points, penalties etc, all through a computer interface. In the end, they hit submit, and we can pull from a master database all the information about exactly what the team did during the match. (look for this to be released for other teams to use soon - almost done working out kinks).
Pit scouting is a good way for students to see other teams, perhaps they dont know everything about every robot in existance, but I have to echo Ben's thoughts here... help them LEARN. This is not about being the best at everything you do, its about learning. Maybe they dont seem to care because they dont understand, or maybe their passion is animation and they are just trying to help out the team. Who knows... take a minute, and educate instead of getting frustrated.
