Hi Daphne,

Thanks for your work on the guidelines & checklist...I've made some  
comments below.

Have a great weekend everyone!

Personally, I am very familiar with Nielsen's 10 Heuristics and would  
like to use them for documentation of problems in my walk-thoughs. I  
think most of the items our longer checklist can be categorized under  
these 10 heuristics, and 10 is about as large of a number as I think  
it's reasonable to ask folks to keep 'in mind.' Here is an example of  
a checklist that categorizes specific things to look for under  
Nielsen's 10 heuristics: http://www.stcsig.org/usability/topics/ 
articles/he-checklist.html. I can help group our longer checklist  
items under Nielsen's heuristics if that is helpful. It may be  
easiest to have folks read our longer checklist (http:// 
wiki.fluidproject.org/display/fluid/UX+Walkthrough+Heuristics) right  
before they begin each walk-through to give them specific ideas about  
things to look for, but only use the 10 heuristics for reporting  
problems.

Sounds perfect!

How should we document accessibility problems found with Colin's  
guidelines? I always think about the Web Content Accessibility  
Guidelines checklist when looking for an accessibility checklist:  
http://www.w3.org/TR/WAI-WEBCONTENT/full-checklist.html, but this is  
probably too long and perhaps too focused on things that are 'under  
the covers.' I wonder if we could pare Colin's list down to a "top  
10", similar to this one: http://groups.sims.berkeley.edu/usable- 
accessibility/Tutorial/tips.php?area=top+ten ? We could also read his  
longer document, as I suggest for the usability heuristics, prior to  
testing to give us a good general overview, but also have a list of  
actual heuristics. I think a concrete list will be make it easier to  
look for trends in problems across evaluators and the applications  
than it would be if everyone wrote up their own description of each  
problem.
