When I try to retrieve a user (using http://www.twitter.com/users/show/stephenfry.json), the double quotes are not escaped in the user description ("description":"I'm blacked out: Stand up against "Guilt Upon Accusation" for New Zealand http:\/\/creativefreedom.org.nz\/ blackout.html"), which means that it can not be easily converted from JSON to a Javascript Object.
Has anyone already encountered this behaviour?
