To advertise my blog, I usually use facebook, yahoo buzz, and digg. Up until recently I have had no problem; I input the specific link to the new blog and it comes up with a preview of text plus a thumbnail. This week all of these sites are no longer able to come up with a preview of either text or pictures. When I input the URL it comes up with just the generic URL, no preview of the article or picture.
The only thing that I've changed in the past week has been updating my plug-ins: EmailShroud, Dynamic Headers, Google XML Sitemaps, and Robots meta. I have gone through and deactivated them one by one, with no improvement.
I have all the appropriate meta tags and it seems like search engines are still able to pull the appropriate information off of my site. I'm at a loss. Any help or suggestions would be much appreciated!
Thanks in advance!
