THING 17: THE LEARNING 2.0 SANDBOX WIKI
The PBWiki Tour and PBWiki Video links on the 23 Things site are obsolete, taking you to the dread 404 error message. This Thing could use a little updating, and not only in the broken links to tutorials. A cruise through some of the other wiki hosters, and a more informative piece about contributing to wikis (including such concepts as create, edit, protections) are in order.
That said, I posted a book to the Favorite Books page on the Learning 2.0 wiki (and saw postings from some classmates, along with their favorite reads, which was the most fun part of the exercise). I didn't want to post my blog, though--the page is kind of a mess, and I didn't see anyone else from 635 there. So why contribute to the chaos?
