Do I see others doing so? sadly no.
I feel like a lot of the replies to my comment didn't read to the end, I agree the implementation is bad. The whiteboard just isn't actually the problem. The interviewers are.
Unless they change mentality to "did this candidate show me the skills i am looking for" instead of "did they solve puzzle" the method doesn't matter.
It's all well and good that you and other "wise interviewer" commenters on HN actually grok what the point of interviews are, but you are unicorns in the landscape.
> I know many interviewers also didn't get it, and it became just "do you know the trick to my puzzle". That pattern of failure is a good reason to deprecate white board interviews, not "I don't write on a whiteboard when i program in real life".
