PDF vs HTML for organisations

The Australian Government recently released a study into the Accessibility of the Portable Document Format (PDF) for people with a disability, which Duff Johnson analysed very effectively.

I can agree with almost all of Duff’s points, and it’s covered so well I didn’t feel I needed to check the source …

ARIAs with Flash, Flex, and AIR

Adobe T-Shirt: Accessibility is not just HTML anymoreI.e. Accessible Rich Internet Applications with Flash, Flex & Air.

Strange sIFR / screen-reader bug

I was writing a little accessibility article for .net magazine about text-replacement techniques, including sIFR. I was blithely saying that "yea, don't worry, it's fine" with a couple of caveats. But, rather than rely on memory I did a quick test, and discovered something strange.

CMS editable Flash

The Defacto-CMS website carousel widget.With all the fuss over AJAX and Flash accessibility you get, I thought it might be worth outlining the process we used to create a Flash/AJAX widget and highlight one of the advantages you get with this method. It also means that the use of Flash has no impact on your Search Engine Optimisation.

Note on Non-HTML formats
