Some people probably know this already, but when someone posts YouTube videos here they break and cannot be viewed. I'm not sure why or how this happens, but whatever the cause this should be fixed.
My way of grabbing the URL is by quoting the post and in the opened tab select the URL and paste it into a new tab. Not horribly efficient, but I haven't found anything quicker.
Kudos to anyone putting the original URL below the embedded video.
