This never really took off (Greg Hall actually posted an audio story about some of the reasons he thought might hold it back) but it's a nice slice of history.
Should we embed that widget here?
Yes, that would be great. I couldn't figure out how that worked.
Doesn't seem like we can embed arbitrary HTML. The recommendation from the Discourse folks is oneboxing which happens automatically. Unfortunately only the P2PU logo shows up when I post the soundcloud like.
