Folks who want to learn more about computing (not the same as programming) seem to have a few options, in decreasing order of granularity/increasing ease of approach by the general public:

2. Detailed, often informal, accounts of how things work, usually written by devs for other devs (on YC, HN, etc)
4. Wikipedia, community wikis
5. Technology journalism
