Can (and should) we enable that feature on GIS.SE? I think video is an important medium for both visualization and as a learning tool in GIS.
This is a good idea but there should be some restrictions and rules for linking videos. However we consider that it makes people to guide easy way with sharing videos rather than writing.
Besides no one can guarantee that anybody share illegal and abusing material or violating the rights of the user on this site.
So it should be discussed anyway!
