The point of the “rules” is to allow ideas not to be shot down before they have a chance to be grown upon. Of course, in this instance, things like the “heart rule” cannot apply to the original topic due to it bringing in an old conversation into one post so doing as everyone else has here and +1ing the parts you like is, of course, perfectly reasonable. I’ve amended the link accordingly.
Go ahead and raise discussion points. So long as they are driving the conversation forward.
I have also updated the ‘rules’ @adam_cameron - made them ‘guidelines’, hopefully they will feel less draconian: About the ideas category
