IngBoo has just released the Facebook Like for Tags plugin.
This plugin converts a standard Facebook Like button from a one-time sharing feature to a one-on-one relationship for ongoing updates and sharing based on tags (keywords) or categories defined by you, the blogger/author. You will see increased reach and revisits as a result.
This news is presented by IngBoo, the developer of this plugin.
License: The plugin is free to use and released under GPL.
