Okay, so the wiki is looking better and better. I've given each tutorial it's own page and added consistent navigation elements for all the pages. Of course, without CSS, I'll have to edit every page if i want to add a new category, but whatever. I'll hold off on that for as long as i can. I think I've covered the main areas, and profiled the main representative sites. I still find new things all the time, but I'll add them to their main categories first, and monitor them to see how popular they become.
I've got a main blog where I keep better track of the wiki and other of my library projects, at http://supercrazylibrarianguy.wordpress.com/
That has links to all my profiles, wikis and other blogs.
Thanks for all the suggestions and support, and feel free to use or share the wiki as you need to!
