...I'm sorry what?
Also question to coso, I forget, how do I post a link so it previews in the status?
Two points:
Not every site supplies the metadata to make a preview.
Previews are "lazy-loaded" here. They get pulled in when someone interacts with a posting, or after "a little while".
@lacuda you can try favorite button, but does not work always as ^ mentioned.
@lacuda If one's available, you can delete and repost, and that'll bring it up, at least that's worked for me
@lacuda link previews depend on the site and also interaction here =)
