A mindburp (or burp) is something you need to remember.
Maybe your brilliant mind reminds you at a really bad time (two seconds before an important meeting, or -even better – the day after an important deadline). Or maybe someone else reminds you – two seconds before they go on holiday – sayonara and enjoy the burps (You know that person, we all do).
Simply put – a burp is a todo, a mental note put down on a piece of digital paper.
