Often, a video can be a great help to visualise a problem.
But on many questions, the person asking just links to someserver.sometld/somedir/somevideo.someEsotericFormat, which might not even be playable by other users (Let alone downloading huge files from untrustable sources).
Wouldn't the best way be to upload the video to a streaming website (e.g. youtube) and link to that?
Should advice like this be added to 'how to ask questions'?
