> Technology has not improved on the blackboard at all. I think whiteboards are an improvement on blackboards.

  Except for the fact that 99% of the time when you pick up a whiteboard marker it is dried out. Chalk doesn't do that.

    And whiteboards eventually stop erasing well. There are some huge whiteboards at work that I’ve been trying to resuscitate but none of the remedies I’ve read about online work very well. Whiteboards seem to last 5-10 years, depending on usage.

      Blackboards also stop working eventually. What the means is that repeated writing, erasing, occasionally using water to clean them completely, makes tiny little holes in the paint. Then when you write, the chalk gets into the holes and it doesn't erase well with a standard eraser. So you have to use more water, which causes more damage... Blackboards in universities are often painted over with new paint after a few years. Of course, this is relatively simple maintenance.

    I just really don't like chalk dust, others have a higher tolerance I think.
