Because I've shared so many Connections coding tips and how-to's, I'm often asked to help provide some guidance on how to create an application from scratch that integrates Connections with product X.
This video came to my attention last week and it's pretty cool. It starts with a demo of what the application is (a portlet that can simultaneously update your status in Connections, Twitter and Facebook, if enabled by the end user).
There are several things that really stand out in this demo. First, I really liked how the video shows that you can use the standard Java library provided by Twitter. Second, the demo shows how this same application looks like from an iPhone (or any mobile device) with no additional coding. The only thing that had to happen was to add the 'mobile theme' in portlet factory and voilá.
