Currently this application works fine even after March....if it works then i think this is the best twitter application just because of event feed integration.
API v1.1 migration period When we release version 1.1 of the API we will simultaneously announce the deprecation of v1.0. From the day of the release, developers will have six months to migrate applications from v1.0 to v1.1. For developers who are already making authenticated calls to the API, this migration will be relatively easy, and should only involve updating the API endpoint, and testing your application's behavior against the new rate limiting policies. For developers whose applications are accessing the API without authenticating, you will need to update your applications to use OAuth.
