Devs, Before today calls to statuses/replies [1] would return only tweets that were prefixed with a @username. As clients began to recognize the value in mentions of a @username anywhere in the tweet, they opted to perform a search for @username to get the superset.
Twitter agrees [2] that the definition of a reply has changed, and as such, calls to statuses/replies contain any tweets that include a mention of the authenticating user. If your client has been using the Search API to retrieve @replies, you should begin to migrate to statuses/replies method as it now best practice. 1. http://apiwiki.twitter.com/REST-API-Documentation#statuses/replies 2. http://blog.twitter.com/2009/03/replies-are-now-mentions.html Code on, Doug Williams Twitter API Support http://twitter.com/dougw
