I’ve spent the day reading journal articles, both popular and academic, about the political importance of twitter.

Twitter has grown so precipitously in the last few years because it resolves the “problem of voice” in many societies. Put simply, we all want to be heard, but we don’t know how to articulate what we believe, see or experience or we don’t have the megaphone to put those perceptions out to the mass public.

By giving you a medium that, in its architecture, allows you to quickly and effectively proclaim yourself, Twitter provides a way to “talk to the world” by allowing you to follow or be followed by a vast number of people. It is broadcasting in a way that Facebook isn’t, since it is based on social proximity. In addition, Twitter’s 140 character limit forces you to be pithy. The economy of words, as Orwell or Hemmingway would attest, increases the impact of the narrative being presented.

Whereas Blogs or Facebook are roundhouses, Twitter is a quick jab. But as fans of boxing know, the accumulation of jabs can be very effective in setting up the big punch. Hashtags allow a barrage of jabs to breakthrough the attention economy, by allowing the accumulation of voices in one package.

But does this mass expression of voice change anything. The jabs have to be followed up with something more substantial. It requires an organizational infrastructure that can build upon the agenda setting success of a viral hashtag campaign to mobilize voters, raise money or pressure elected officials.

This part of “hashtag activism” is not well understood. How does Twitter modify or subvert the traditional policy making process? Agenda setting has always been a part of this process, but new technology is impacting it in poorly understood ways.
