Arqade has the ability to embed YouTube clips within a post as long as the YouTube video appears on a line by itself (example).
Searching about, I found 162 posts that reference "*.youtube.com" and another 21 posts that reference YouTube's URL shortener, youtu.be.
Would it be possible to get this embedding functionality here? It shouldn't be any more disruptive than post imagery, which is pretty well accepted here.
