The window is not shown unless a reader clicks the Discover icon or one of the auto-tags. So it does not really take much space on your blog. When a user clicks a related post, it is open in a new window/tab. When that window/tab closes, it will return back to your blog. The objective is to give readers broader perspectives. Although you will be showing other bloggers’ links, in return, other bloggers with the widget will be showing your links, enabling readers of other blogs to discover your blog as well.

The strength of the Auto-tagging and Discovery Widget is that it automatically finds and assigns to each post tags that have consistent meaning and are statistically significant across the blogosphere.

With this Widget, your readers will be able to discover other posts by you and by other bloggers, and news related to your post using the auto-tags, bringing them broader perspectives. It enables your blog to be discovered by readers of other blogs in the community.

The Widget finds auto-tags by putting your blog posts in the context of millions of other blog posts and news, and finding the most appropriate auto–tags using an natural language processing and relevancy analysis algorithm.

A live demo is at http://stack-up.com/stack. Move down to the end of each post, clicking on the Discover icon or one of the auto-tags will bring up the widget results.
