At the office, we don’t use whiteboards much. We’ve got plenty of glass surfaces. When we need to brainstorm, we just take a marker and scribble on the glass. Then we snap a picture to remember what we said during the meeting.
We do use one board though. It’s the #shitclientssay board. A hall of fame of sorts. Something we have a look at each time we want to start banging our heads against the wall.
