There is a lot of deliberately deceitful information out there and I would like to build something to counter that, so does anyone have any thoughts on an app or system for helping find truth? I don't want to make a 'fact checker' site that is just some other arbitrary authority.

I could make a sort of url checker, where you toss in a url of a video or a blog or whatever and it spits out the most voted arguments for and against that resource's validity, and a user can 'vouch' with a comment for resources as well.

I could make a system just for tracking politicians and parties, who votes what on what bill in a nice easy to read and understand format.

Basically is there any sort of system anyone would want that's geared towards rooting out deception and finding truth?
