Say you're on a webpage about a particular thing ("entity"). Click on Entity Explosion to get information about that entity, and an explosion of links to other sites about that same entity.
Even before you click, the icon will light up red if the URL you are on matches a set of formats for which information may be available. Once you click, it will either turn green if it can find information, or black if it can't. [view the demonstration video here: https://www.youtube.com/watch?v=eRnqoJyi92w

The URL and language (only) will only be sent out as a part of a query when you click the extension, so your browsing privacy is protected.
This extension is in development, so you can expect occasional changes. I would welcome feedback.
