Social Impact Widget

The plugin creates a shorter link for every blog post, so instead of <code>http://kovshenin.com/wordpress/plugins/twitter-friendly-links/</code> you can use <code>http://kovshenin.com/712</code>. Sweet, huh? Here’s a video presentation: <a href="http://kovshenin.com/archives/video-twitter-friendly-links-for-wordpress/" title="Twitter Friendly Links for WordPress" rel="nofollow ugc">Twitter Friendly Links for WordPress</a>

YES, I do consider feature requests, and that is what makes this plugin work. The discussions go here: <a href="http://kovshenin.com/wordpress/plugins/twitter-friendly-links/" title="Twitter Friendly Links" rel="nofollow ugc">Twitter Friendly Links</a>
