Discussion of science, at least at a point when you can't just say 'This is the currently accepted model' (and that is the end of that) is something which is hard to engender without having sufficient people with the ability to discuss high level science, which is a rather circular problem when you consider that the entire issue is acquiring people with the ability to discuss high level science.
Discussion about science, on the other hand, doesn't have to discard the layman; there is no advanced mathematics, which is generally the problem area, given that any qualitative results will be formed from the mathematics and so aren't really available for discussion without rather more explanation of the possiblities that is really healthy; instead, there is basic reading, comprehension, and the like. Examples of talking 'about' science would be discussing the scientific method, your funding example, and the like. It's intellectual, and very accessable to the interested layman.
[edit]
To an extent I did use rather wishywashy language; discussion 'of science' as compared to discussion about 'science', if you catch my drift and I'm sure that you do.
