For some reason, when we link to posts from our blog's Twitter feed (twitter.com/5albums), they have stopped 'previewing' properly (i.e. you can no longer expand the link to see the title and a lead photo within Twitter).
These links use to preview properly, and this has only stopped happening recently. We note that previews for links to other wordpress blogs are still showing up for other users. We're wondering what's changed and if there's anything we can do to restore this functionality?
The blog I need help with is 5albums.com.
