Would love to get your thoughts. What if there was a chrome extension that allowed you to upvote any link you run into over the internet. This way you have a meta layer of human curation over the internet, giving contextual clues as to whether something is really useful or not!
The way the question is worded, it seems to me that you have a product idea which you want validated. I'd be wary of this method of building sideprojects because it will close you off to other, possibly better ways of achieving your end goal.

If you look at this idea with squint eyes, in a way, it has already been implemented. Facebook and Google show you posts you are likelier to read ("trust") because of all the profile information they have on you. Each Like and Share you do raises that article's "trust" score.
Will you be able to become the Verisign of trust? Maybe. Verisign's business is built around maths. What are you going to build your "Trust" number on?
Great idea, major issue to overcome is going to be reaching critical mass. You could probably overcome the apparent lack of pre-existing users and data by stealing data from web of trust and digg clones.
That is a fantastic idea! I was thinking about the critical mass, and this never occurred to me! Do you think shipping it as a chrome extension is the best medium, or is there another avenue I'm not seeing?
