This plugin adds a Like-Button after every post/page you choose (you can exclude Posts/Pages/…, These excluded sites will have no Like-Button).. Before or after the content as well as a sidebar-widget.
The Like-Button-Widget includes a little Like-Button-Generator to make it easier for you to get a Like-Button to your sidebar. It also adds a Shortcode for your like-Button. It is also possible to choose the XFBML or the iframe-Button. You could also choose the position of your like-button within the post/page.
