This is one application of #tagcoding. Many phrases of a state-of-the-nation address (SONA) can be tweeted with the suitable hashtag. After the SONA, search for the hashtag will show the statement as well as all other tweets about the same topic. After a while, you can easily verify whether and to what extent a promise has been implemented. Cool, isn't it?

The example of this tutorial is no longer available as the platform on which it was created no longer exists (it was Storify).
