> Like these things known as "pen" and "paper", for example.
When you need to share this pen and paper, you use a whiteboard. I don't understand this hate for whiteboards, which are a cross-industry cross-profession standard (including medical) when collaborating.
One of the more interesting things I have noticed is that happy engineers have a little free time each day. They aren't under crushing pressure at all times. To this end, it's very common for whiteboards to accumulate drawings and doodles. This is often turned into "the elaboration game" where one doodle is built upon (by a little or a lot) every now and then. This is probably because coding is problem solving, but also because it's a creative endeavor. Engineers who are happy tend to work around other happy engineers and those engineers are all creative with free time.
