Post Description not showing in social media links

Hello,

When I post links to my blog on social media, the description section just repeats the post title. Screen shot of what I mean: https://dl.dropbox.com/u/3704634/post-description.jpg

Example of post: https://www.unframedworld.com/2012/04/super-secret-photoshop-technique-non-destructive-high-pass-sharpening/

After researching the issue and scouring the WordPress codex pages, I think this has something to do with my header.php. I see this code and assume it is printing my post title, description, and key words in the page source.

Thanks for you expertise! I know you totally got this.
Andrew
