Cool idea, but I don't see how it can ever possibly work with the amount of astroturfing and frequency/ubiquity of undeclared paid advertising.
You're ingesting highly biased, sponsored, astroturfed content. What measures have you taken to filter Youtube reviews down to the ones that haven't been sponsored, and likewise for Reddit? Otherwise it's just garbage in, garbage out but wrapped in fancy, legitimate-looking packaging.
It's the eternal September problem. Reddit was a great source of honest reviews until everyone figured it out and started to take advantage. Services trying to capitalize on it may be well-intentioned but it's only going to accelerate the enshittification.
