As people watching the impact of social media in the events in Egypt know, Facebook, Twitter and YouTube played a role. Today, Microsoft’s director of public sector engagement, Mark Drapeau, sent word that the Redmond-based software company’s open source ideation platform, Town Hall, has been deployed at nebnymasr.org to collect ideas.

The highest profile implementation of Town Hall to date was for crowdsourcing ideas in Congress for the incoming Republican majority in Congress at “America Speaking Out.”

This Town Hall instance and others show how citizensourcing platforms can be tailored to channel feedback around specific topics, as opposed to less structured platforms. As governments and citizens try to catalyze civic engagement using the Internet, creating better architectures for citizen participation will be critical. Clay Shirky’s talk about the Internet, citizenship and lessons for government agencies at the Personal Democracy Forum offered some insight on that count. Using taxonomies to aggregate ideas instead of a single list was a key takeaway.

To date, the Egyptian citizensourcing site has logged a few dozen questions and votes. Whether usage of the site will grow more or not is up for debate. The network effect may working against it. As ReadWriteWeb reported last week, Egyptians are using Google Moderator to brainstorm Egypt’s future. Wael Ghonim, the Google executive who played a role in Egypt’s recent revolution, started a Google Moderator page for Egypt entitled, “Egypt 2.0, what does we need? What are our dreams?!.” To date, the Moderator instance has logged 1,361,694 votes for more than 50,000 of the ideas submitted by nearly 40,000 users.
