I have been spending a lot of time learning how to write Social Modular Content. I have learned enough about Facebook Applications to make an app, “Hometown Throwdown.”
Now I am focusing on the Google Gadget / Widgetbox OpenSocial platform.
I made a simple Flash widget based on a picture I drew (and scanned!). Flash is the only format favored by All of the OpenSocial platforms. When writing these apps, you have to consider the “host platform” software requirements, rather than the end-user. For example, I normally stay away from Flash 9… but that version is what the big guys like Myspace demand.
The hipster approval widget OpenSocial version is on the right. In the iGoogle version and Facebook version, the installer is asked some ‘test’ questions before earning approval. They also feature RSS feeds from hip blogs Cool Tools and Pitchfork Media. Finally, the Facebook app features a Google Map with the result of ‘dive bar’ search local to profile’s network.
