What in the world are these little icons trying to tell me? I don't have the smallest clue.
And that brings me to the question - what are some things that you assume that others know when you're giving a message that they may not understand? Often we can be blind to the bad icons we are putting out there. So it's worth asking others if that "icon" we made communicates what we intended it to. The best "others" to ask might be those outside of our working realm.
