Music is what leaps out at me as missing. Also, why only "early" and then "creative" writing? For most people, in most careers, persuasive writing (for example) is far more useful than, and just as difficult to learn as, creative writing.
Although it's interesting to think about what we'd have, I'm not so sure it's a good idea to have a lot of threads like this. Inevitably, some discussions will overlap several threads, while at other times, a focused discussion on one aspect of a subject might get lost among 78 pages of posts on one of these subjects. I think it is probably preferable to let threads come up as they will. (However, one thing I'd like, if this forum had it, would be the ability to tag threads and search by tags. That might serve the same purpose rather better, I think: we could agree on a set of tags, like "mathematics", "science" etc., and use those to tag relevant threads. A quick search at ubbcentral.com didn't show up that the software this BB is based on has that capability, though.)
Going back to the overall topic, I agree with those - e.g. Breakaway4 at the very beginning - who emphasised the meta-learning skills. If someone gets good at identifying what they want to learn, and at learning it, with or without interaction with other people, they're away.
