Yes, I know about MMP. It was introduced much later, after people were already very used to doing things in an individualized manner. From what I'm told MMPs aren't used much.
So you think that even new users (I believe many users arrived after MMP were introduced) are not using MMP due to bad old habits of the other users? I've had a hard time trying to convince some users to use a MMP; I think it's not trivial to understand what models actually work and are liked.
Toolserver's model is fundamentally different. It's based on an old concept of shared hosting. Labs is built on a model more like a VPS (really more like EC2). Due to that, it's possible to give users far more rights. MMPs aren't a very elegant solution. I'd prefer not to force an inelegant solution into a system that allows much more elegant approaches.
I'm not a technical person but yes, I can probably understand that MMP is not very elegant. But, do you think users are not using MMP because they're not elegant?
