Thanks, the accessibility issue did have me concerned about
captchas, though
as I thought about Thomas D's "cognitive"
suggestion, I wonder if the audio
link couldn't be a simple, brief podcast that provided
information on
alternate access methods. It's not as if it had to change
very often. E.g.
"Please email us at [very clearly read email
address]."
I'd still like a cognitive test that ferreted out real
estate websites from
content we would actually use, but that's another story.
