So you nailed what I've already argued to many others, which is reviews are relative to you. I completely understand your point, but it's hard to achieve what you desire w/o being intrusive. To highlight relevance, we'd have to get users to fill out a questionnaire about their race, age, interests, etc. This is a possibility down the road I suppose.

That's why I created the 'trust' feature though. If you spot an Indian reviewer, add them to your 'trust' circle. Later on, we can get smart and provide 'trust' recommendations for you, but that's a future feature to tackle.

Also, you're correct, voting reviewers have existed for awhile, but they're hardly highlighted by those sites as important. We feel like by encouraging voting from day 1, we can start a culture where it's widely used. Maybe that's a bit naive, but emphasizing how important it is to site functionality should hopefully encourage use (just like how it's used in Reddit/HN).
