I personally think that a Wiki would be much more useful and easier to pull off than podcasts and ebooks (I like both of those but they both take a level of commitment that will be tough to find on a regular basis).
We have mountains of information on this forum and lots of extremely knowledgeable people that could be put into place and maintained in a Wiki very nicely. Then, instead of needing a podcast, you can have a topic that describes how to do something along with pictures, links to forum posts, and links to web pages and Youtube videos. All of that information could be made much more accessible and maintained by the larger group without a time commitment for anyone (except maybe mods to patrol people that screw up the information).
The current problem, in my opinion, is that we have these mountains of information but it isn't readily accessible to people without doing a Google search and a lot of reading lots of different posts. If it was in a wiki then new people could go there to learn things first and then ask questions if something isn't clear.
That's my $0.02
P.S. Now actually might not be the best time to try big changes like this since the new mods are busy learning their new craft... but it's good to discuss
