Yeah i don't think it's worth doing for every web app. But I do think it's fair that for instance government websites try to meet these criteria.

It's funny what you have to do to tick a box on a Government form. A long time ago when I was relatively new in the job I thought I was being pranked (ohoho let's noise up the new guy) because I got asked to take a record when I went to site to repair network stuff, of which sites had a wheelchair-accessible entrance, accessible from the street.

o_O

All of them?

There's a door at the front and the back with a gentle ramp down to street level, flat access into the building, and the door is like twelve feet wide and fourteen feet high which is big enough for even the most impractically large wheelchair, surely?
