Great work mate, keep it going! I know one of the things that always frustrated me about steemit was the lack of spotify and mixcloud embed compatibility!
Spotify was added on to @peakd and would be great for Mixcloud embeds for us DJs wanting to share our radio shows from that site as an embed? They are just iframes I think there as well?
Are these in the pipeline? (obviously it's probably not a high priority right now haha)
