Add title/summary line for YouTube previews
Currently, configuring the YouTube API key will allow you to include previews of the video but will not include any form of context - the user must provide this. It would be good to include the title and brief summary of the video in each post, as seen when you share a video from the Android YouTube app to Hangouts etc.

Hi Stephen, I think we already show the title and the username who posted the video in the generated youtube previews (they should be above the video when you post a youtube link).
If the API key is not set up, then the preview just shows "Youtube, unknown" - if this is what you're seeing, perhaps check and make sure your API key is set up properly?
