Bookmark, Share, Simple (2011)
Bookmark, Share, Simple is a Wordpress plugin that was released in March 2011. After installation, it adds a bookmark drawn in HTML5 canvas to the top of every page on a Wordpress site. When this bookmark is hovered over, it lengthens, and clicking on it displays a share box, which shows 6 icons. Clicking one of these icons causes the sharing service for the appropriate site to appear in a popup.
This plugin was discontinued after I moved from a Wordpress site running on shared hosting to a Tumblr blog.
