Keeping kids away from questionable content while they surf the web is an ongoing battle, and there's a new site that's looking to help. Thinga, a kid-friendly search engine, offers answers to children's queries from the company's own content library, white-listed sites or privacy-minded search site DuckDuckGo. Thinga comes from a Yahoo Kids alum who worked on that kid-focused project before it shut down a while back. Those search results are vetted by the team at Thinga to make sure they're appropriate.
