Yikes! I just check my Diigo account and realized I have a huge list of writing / 6-traits resources that I haven't shared. I use Diigo to organize my online bookmarks. I love the ability to create annotations and to highlight text on a web page.
Here's my Diigo List:
http://www.diigo.com/list/wiredinstructor/six-traits-resources
You might prefer to see this list as a slide show.
You'll see the home page of each site I've noted.
Just click on the page and you'll land directly on the site that's caught your interest.

It's free, fine, and filled with good folks and great resources.
Diigo also offers a service exclusively for teachers: http://www.diigo.com/education. The new Diigo Educator Accounts are special upgrades provided specifically to K-12 & higher-ed educators so they can easily make use of Diigo in class and with their students.
