We are, after all, not *coders* but *programmers* and as such, we also program our audience with our words. Sometimes knowing who the audience is, can be difficult however it should not be an excuse for not making an effort. 2023-11-10T07:23 2023-11-11T07:23 https://blog.openmindmap.org/blog/flowhub-collaborative-code-sharing Development has become collaborative but has visual Flow Based Programming (FBP) being keeping up?
