Since this came up on Slashdot, I'm plugging my new site: CommentHow.com

All content will be public domain, Creative Commons Attribution, or Creative Commons Attribution Share-Alike, meaning everything can be remixed. That's why every article has a "Copy this Article" button, letting users base their how-to article off someone else's. That lets them extend it, translate it into their own language, or localize it to the needs and materials of their local context.

Also, Comment/How doesn't limit you to English, which has been a problem for some of the users of Instructables. Pick from any of Earth's almost 7000 languages to browse or post in. (Of course, most of these don't have content in them yet.)
