TAGSExplorer created by Martin Hawksey lets anyone archive Twitter event hashtags and create interactive visualisations of the conversation. It uses Google Spreadsheets as a data source and a simple web interface adds interactivity. I have included a few images here to entice you to have a go. Take it from me – with the video and step by step guide written by Martin it is not as difficult as it appears complex.
Its a work of simple genius from Martin Hawksey.
