The National Theatre of Scotland makes great use of Storify. They use it to bring together comments people are making about their performances.
The Medievalists account brings together (and it is not a surprise given the name), medieval matters.
Museums, such as the British Museum, The Ashmolean, and the Science Museum, are all doing interesting things with Storify. Catherine Fletcher tweeted and storified about the television production of Wolf Hall (highlighting the research). Trove is using it too.
It can be used for fiction, such as this (rather creepy) work by Chuck Wendig.
Other libraries are deliberately experimenting with it, but it would seem a fit for at least temporary collection of material of relevance to local studies.
