Taking a look at two items over the last week and the activity on Twitter. 

The first being @Webconomist (Giles Crouch) and the data below shows the run up to #PodCampHalifax and the number of mentions in relation to the Atlantic Canada social media usage study released. This data pretty much takes us up to 5PM today. Quite the spike, in comparison to a normal day.

Moving on, yet another popular discussion item within the social media space (among many others), is #SOPA. 

The data above was collected through http://manageflitter.com.
