This would quickly trap you in yet another filter bubble, just one of your own creation. Dangerous idea. One of the core principles of the internet should be the ability to discover and encounter information and opinions that you aren't even aware could exist (serendipity?). If user start to limit all their searches to just a handful of websites and their peers it can have a really bad filtering effect.
Besides, do not think about the problem as a techie with a long list of trusted internet personalities. Think about it as a normal user that barely gets technology. The most common outcome would be that they setup once these search sources with some random familiar sounding names (probably news outlet they trust) and never touch them again. It feels it could be a highly exploitable system.
