don't know if this thread is still active, but as I'm unfamiliar with editing wikis, but I'm full of ideas (and I have a big mouth), I thought I'd list some discussion items here. I'm working on the assumption that the wiki should be one of the, if not the, first place new users shouldbe looking to get information.
1 - remove the radios from the rom section, and give it it's own section on the main wiki page - it's too confusing for new users to locate this information under roms
2 - instead of just linking to roms, kernels, radios, etc. from the main page there should be a few sentances on what each is above the link to the new page - something simple defining each term, and some basic instructions on how to flash each (what should be wiped, what goes on top of what, etc).
3 - would also like to see some info on the main wiki page on nandroid (and the importance of nand backups), hboot, recovery info for both amon ra and clockwork, what wiping means and what it does, themes and themeing, and possibly even a section on popular apps and what they do, like setcpu (and what it means to over/underclock), various launchers (like rosie, adw, launcherpro, etc), and various benchmarking tools and what they measure.
I could probably think up a bunch more, but I'll see what kind of response this gets before posting more
