I also think a lot of people fall into the trap of "It's a solution so it should work, end of". They seem to think that no additional tinkering is needed to optimise it for your school.
2.4 was a great point in case in that those that fiddled the most seemed to benefit the most. In my opinion I would say we had a great system running on it, with RM's stuff and bits we had added to fill in the gaps. I used to feel a great pride when you would find a 'hacking' site describing ways to get round systems and either be able to say, "fixed that, stopped that, that doesn't work" or go and test them and find something you had put into place all ready stopped it. But there were many others who hated it and though it was the worst ever because these hacks worked.
Though that opens the debate of should a solution such as RM's, or anyone elses, need additional bits added after.
