I've been reading Richard Gabriel's book, "Writers' Workshops & the Work of Making Things". I'm really liking what I've read so far. It speaks a lot to what I think about collaborative learning --- what we do when we read and write each other's programs to give and share the gift of making.
In some sense, a mailing list like email@example.com tries to --- perhaps instinctively --- follow the writers' workshop environment. There is satisfying work in building communities that help each other; I would like to continue with it.
Besides reading, I'm continuing my study of PLT Scheme, and think that I can contribute to the documentation-for-mainstream-programmers-is-missing problem. I'll start by attacking classes, since that'll be the thing that Java programmers will reach first, and I'll probably try to tackle MrEd next.
Last: sometimes I'm too eager to jump into a question and write something that I think is helpful; I should watch out not to reveal too much, lest I do damage. The lessons that John Holt learned in How Children Fail should always be at the back of my mind.
