Hashtags are a way of categorising and arranging content on social media – and a good tool for finding audience-generated material.
For example, you can:
search using established hashtags
ask listeners to use a specific, preferably unique, hashtag to tag photos, posts or other content that you want from them
find eyewitness reports, stories or expert opinions under hashtags on Twitter and Instagram
follow hashtags in the Instagram app and via TweetDeck on Twitter
In 2013, Sisuradio (SR's finnish speaking department) launched a theme week with its own hashtag, #vågafinska, on experiences of being multilingual (Finnish and Swedish) in Sweden. The plan was to reach the group of Finland-Swedes living in Sweden, but in fact they reached not only the target group they were hoping for but also a new audience.
A large number of listeners made contact via social media, and Sisuradio received a lot of stories and experiences to share on FM. The response was actually so great that the project was nominated for the prestigious Stora radiopriset radio award, and many of the stories submitted via social media were collected in a book that was published in 2014. Most of the reports came in via Twitter, but one lesson that Sisuradio learned was to offer the audience different ways of participating: social media, email and phone.
