in_reply_to_status_id is populated when a tweet is a reply to another tweet. The status_id in this context refers to the tweet being replied to. For this field to be populated, the "reply tweet" also must begin with the @username of the user being replied to.
A @reply in XML: http://gist.github.com/620548#file_reply.xml in_reply_to_user_id indicates the @user being mentioned by primary key "id", which never changes for the member though the screen name might. in_reply_to_user_id may be populated on a @mention (which does not have a referenced tweet in in_reply_to_status_id). A @mention in XML: http://gist.github.com/620548#file_mention.xml And while Thomas is right that it's great to explore with an API console, I'd personally recommend that API console at http://app.apigee.com/console/twitter instead of the one we provide on dev.twitter.com.
