Well, http://sites.google.com/site/arclanguagewiki/ is up, running, works, is available for editing for anyone who want to edit it, and I've been planning to continue to contribute to it myself. So... certainly anyone can post material anywhere they want, including a different wiki platform if they like it better, and if it's something useful to Arc we'll include links to it just as we include links to other useful material, whether published in a wiki or a blog post or whatever... but I personally would be looking for a more definite reason to post somewhere else myself.
Is there something specific you don't like about Google Sites?
Some of the things I was looking for:
- no markdown. I despise markdown syntax (when writing about code) with the myriad special syntax that I can never figure out how to escape.
- a way to plug in code examples from my upcoming "pastebin for examples" site, which I hope I'll be able to create a Google gadget to do.
- a clean layout without a lot of junk gunking up the page
