Project Gutenberg Made Accessible
Yep. To me, and probably many others who are exposed to human-computer interactivity issues, accessibility has a particular definition including:
Accessibility refers to ensuring that Content is accessible, ie. ensuring that Content can be navigated and read by everyone, regardless of location, experience, or the type of computer technology used.
The original text format is obviously tailor-made for accessibility. The HTML format will make the data more useful (perhaps even more usable?) for those people who have an HTML browser, but will make it inaccessible for some users.
Overall it's a really poor choice of wording in the Slashdot title and summary. But then again, Slashdot and many of its visitors seem to get the terms accessible, usable and useful totally wrong while they chide others for misusing hacking and cracking. ;-(
