Would this be a good place to collect (via links) various matrices that are available? I have seen several recently that are very good and up to date (CITEDd TechMatrix is a good example). I know there are other similar matrices and resources are out there. It would be nice to go to a site that has a collection or a specific area where these are collected, rather than searching for resources all over the web.
I think that the AT Wiki would be a great site for this as you can have a list of sites on one page with a description of each link vs. having several different messages here. Brian set it up a few weeks ago and a few of us were going to start working on it but we just haven't yet. So, this might be a great reason to start using that site: http://assistivetech.wikispaces.com/ You could add a page for matrices and others could add to it.
I look forward to reading other people's responses.
