When I speak to litigators, many of them tell me that as part of vetting a claim, a web search on the background of the principal is now standard practice. And I don't just mean the potential adversary; they search on their potential client as well.
If you're going to perform a search anyway, you might as well do it in as few keystrokes as possible. Obviously you'll use a search engine like Google, but the reason a "scouring" program like snitch.name is helpful is, not only does it allow you to select multiple platforms to search, when it finds results, it produces them in graphic format on a single page.
It's an excellent companion to standard search.
