Continuing the discussion from STL Import/Export:
That person would be me. And I base it only on the use of check marks to earn a badge (“Learned One”) which one can choose to display with every post you make.
To me, “Learned One” is a recognition of the assistance you’ve given to others - and it is thus for others to decide (by collectively bestowing 10 check marks on your posts) if you have earned it.
Once earned, however, I have no problem with checking the box on your own post. I assume that those who do have the wisdom to do so when their own post is, indeed, the best solution to the problem presented.
