In late 2009 early 2010 on the eve of Presidential Elections we came up with idea to use Twitter on covering election process. Twitter is supposed to be the fastest tool to deliver first-hand evidences from witnesses.
We created a platform which accumulate messages. Moreover, we used a set of hashtags to mark messages (tweets). National level reports - with #elect_ua, reports of election fraud - with #elect_sos, regional reports (we had 5 key regions, 10 more joined us later) - by the name of the region - #elect_od for Odessa, #elect_te for Ternopil etc
How did it work? Pls, see presentation:
