We recently introduced embedding support for comments. To make it more interesting, we added a new feature to convert bare links to rich link previews.
Will be converted to...
All you have to do is to add a link in a new line. To make it work, the link
must be publicly accessible,
and must have Open Graph or Twitter meta tags.
We consider link previews as embeds. So, the website has to have embeds turned on (see the embeds/KaTeX announcement for more details on it). Maximum embeds per comment are 3.
What are your thoughts on this little new feature?
