I think it’s that nobody knows just exactly how to package a default site?
Well I’d have to disagree with that one as I could do it if I wanted but I don’t want to 😉
The reason being that tastes are different between people and there are a lot of people out there and I can’t be doing with anyone saying what you said about one of my designs as I would probably cry 😉
Seriously though I think you would need so many templates to make it a good thing or people will just take the one they like the best and then saturate the web with it. With the templates that you get with ExpressionEngine they are meant more for understanding how the system works and they do that admirably. I even find myself looking at the main site/index page every now and then as there are items, particularly at the bottom of the page which I always forget about so in that respect they are helpful 😉
Also for a beginner I doubt that they are going to get their site up and running within a few days due to needing to learn everything and the templates that are there do that quite well I think.
Just my two penneths worth though not having a dig honest as I totally value your opinion and see where you are coming from on this one but I do think there are a lot of variables involved 😉
Best wishes,
