Isn't it weird (and cool) when things just… come together?
Here I am reading the usual three or four books at the same time (chief among them is 
Don't Make Me Think!: A Common Sense Approach to Web Usability, Second Edition)
… in this case on internet publishing usability (in preparation for very possible upcoming work on an online education project)… and on the drupal.org aggregator there arrives a post about usability sprint with several open source projects in Mountain View, and talk about getting usability involved with Drupal… and indirectly, another OpenSource project is mentioned, Hyperscope
where a whole new panorama opens up for me, on the subject of not only making usability central to the upcoming educational project (as suggested by the person about to contract me), but rather that… usability, in form and substance, is spawned of… the theory of knowledge aquisition (actually, access to knowledge is more the term) itself!!!
Check out Hyperscope and be as amazed as I am right now about the history of hypertext and its connection to access to knowledge; and bless that post war 1940's 1950's 1960's positive thinking ("party like its 1968" is the expression used!!!).
Right there is the link to useit.com, the site of the author of two of the other three or four books I am reading, Jakob Nielsen, and the blurb for Multimedia and Hypertext – The Internet and Beyond … this is now vaguely added to the list of books I am reading (er, scanning). Anyway, check out what it says about the history of hypertext, astounding.
