Fencing-in the
      habitat
How to do the right thing
   and get it wrong


Christian Heilmann, AbilityNet, London, April 2008
We’re here at an accessibility
        conference.
Most likely all of you want to
 create accessible products
 and know why we should.
Genuinely usable and
accessible sites and products
       are very rare.
Sites that claim accessibility
and companies that claim to
make your product accessible
           are not.
People only grudgingly
 embrace the need for
    accessibility.
How many times where you
asked to provide numbers of
how many disabled people a
          site has?
Don’t play the game of
numbers (buying power of
     disabled users).
