I am simply repeating the news: From the WordPress Plug-in page, it states: “This plugin has not been tested with the latest version of WordPress.”
Either way, and regardless of the reason, Genesis is a commercial product and should come with commercial quality updates to plug-ins/widgets in a timely fashion.
I understand that the reason the plug-in stopped working was due to the Twitter API change but that does not alter the fact that whomever was responsible for maintaining it, was not in a position to catch the change and immediately update it so as to avoid disruption of service to the hundreds of Genesis Framework users who rely on what is usually a rock solid platform of integrated widgets and plug-ins.
