Now that the JSON cat has been let out of the ajax bag, I feel that I
can contribute with how I "do ajax".

I use the YUI toolkit - it just takes away most of the pain. I use the
asyncRequest() method, which is pretty much just a way to get stuff from
the javascript to the server, and deal with the/any response.

The request is just a POST at the end of the day, which I parse the same
as any Catalyst action with params.

I then "use JSON;" [someone will probably suggest JSON::Any] to turn a
perl data structure into a JSON string:

  # return some JSON
  $json = to_json($return_data);
  $c->response->body( $json );
  $c->log->info( $json );
  return;

For me JSON is easy, painless and does everything I need it to.

Also, for me if XML is the answer, I try to ask different questions
until it goes away.
