publicvoit, Today I spontaneously went on the empty #ArtAndPlay stage on #37C3, plugged in my laptop & started to silently demo #Emacs #orgmode to the surrounding people in full-screen so that people were not able to realize which tool I'm using.
I demoed the syntax (lists, tables, ...), spreadsheet functions, export to PDF & docx, task headings, bi-directional links, task dependencies, babel, PlantUML integration, ...
After a while, people started to come to me on stage and asked me what tool that is. 😃
