If you reference venues on <a href="http://foursquare.com/" rel="nofollow ugc">foursquare</a> you may want to include the Publisher <a href="https://foursquare.com/buttons/savetofoursquare" rel="nofollow ugc">“Save to foursquare” button</a> inline within your WordPress posts.
This plugin is a simple shortcode that accepts two parameters:
<ul>
<li>uid = foursquare user ID (numeric) to appear as ‘referred’ by’ on foursquare once saved to a user’s list</li>
<li>vid = the venue’s ID (hash at the end of a venue URL)</li>
</ul>
This was built for my own purposes but am happy to accept pull requests <a href="https://github.com/devinreams/wp-save-to-foursquare-shortcode" rel="nofollow ugc">on GitHub</a> for any improvements to make this more useful to the community: https://github.com/devinreams/wp-save-to-foursquare-shortcode
