This plugin adds the Google Reader Stats to your blog. GRS measures the +1s and views count of each blog feed item on Google Reader and displays it on your blog . The GRS Widget enables readers to easily see the blog’s best content, with the highest overall +1s or views on Google Reader.
Put the <code><?php if (function_exists( 'the_grs_plusones' )) the_grs_plusones(); ?></code> code for post +1s and <code><?php if (function_exists( 'the_grs_views' )) the_grs_views(); ?></code> for post views in your template files (index.php, single.php, archive.php) to show +1/view count.
