It turns out some sites like Meetup.com support oEmbed but don’t link to it using HTML. I’ve upgraded our onebox engine to support providing endpoints for URLs that are not advertised, and now our meetup embed looks a whole lot better!
Thanks a lot to everyone who participated in this issue on github!
The button with interactive click counter is great. The only thing that seems ugly is all the wasted space below it:
Wow, I’m amazed that it looks good where it got put! Given that we had no control over that.
