Just thought i would pass this SEO tip around.
It's especially useful if you export your forums posts via RSS to Facebook, etc. It cures that problem of Facebook grabbing the 1st image it finds when your post has no images. Allows setting a default image to use for Facebook and Google+ posts with no image. Plus of course it adds important Open Graph meta tags to your pages, both on the WordPress blog posts pages and SimplePress forum posts.
Best wishes and Happy New Year to Everyone..
