I just attempted to use the Share button to post my latest post to my FB page, and from the preview (the page that pops up with the little box for comments) it looks like Facebook can't read past the shortlink WP.com provides. There was no content, there was no thumbnail, For a spit second the correct title showed, and then it vanished, to be replaced with:
(No Title)
http://http%3A%2F%2Fwp.me%2FpuKk-2jP/
Manually posting the link worked fine.
The blog I need help with is raincoaster.com.
