Modify the Home Page Title for Facebook / Open Graph

If you’re using a static post or page for your home page, then you have access to the custom Social Settings metabox for your home page, and can modify the default title, description, etc. for your home page. If you’re using a index / archive type blog page, then NGFB relies on your WordPress (and SEO plugin) settings to provide an accurate title for the Facebook / Open Graph meta tags. If this title is not suitable, you can override the default value with a custom filter like this one.
