wibiya

Wibiya enables blogs to integrate the most exciting services, applications and widgets of their choice into their blog through customized web-based toolbars. 
Our platform offers a one-stop solution for integrating, managing and tracking third-party applications.
Currently we offer a fixed set of tools such as creating a blog community via facebook connect, 
enabling twitter alerts on your blog and enabling post navigation but there is a lot to wait for as we will be adding more and more application through time.
