Does anyone know what plugin is used on johncow.com blog under his posts for "Share This" ? I like the way that plugin uses all social networking sites and email. Thanks ahead of time.
It is a social bookmark plugin. You can search the wordpress plugin directory for it. Edit adding the link for you http://wordpress.org/extend/plugins/social-bookmarks/
I use a plugin named "obsocialbookmarker", this plugin can let you choose from over 15 social bookmarking site and it appears just after your post in small small icons.
