Continuing the discussion from Random comic generator:
Every link to a web page that has OpenGraph or oEmbed fields on the page will now be posted as a oneboxed link. We used to do this only for a narrow list of whitelisted websites — now we do it for all websites by default.
So any “bare” links you post should be prettified and oneboxed, if they can be, like so:
If you’re not sure why a link didn’t onebox, it probably does not have OpenGraph or oEmbed fields in it. You can use the http://iframely.com/debug checker to verify or view source on the page if you are just that god damned hard core™.
Please to be reporting any issues or oddities.
