Actually, what you pporose is the best way to lock oneself up to a SYNTHETICALLY narrowed information pool.Any automatic recommender is by definition destined to a limited set of arbitrary rules (compared to a human brain).While giving you an illusion you get all the data you need, you would get all the data THE SYSTEM believes you need.Without thought-monitoring a for recommender to be correct by using you own thoughts, and then preprocessing them via artificial intelligence, any recommender is destined to synthetic but arbitrary filtering.Best solution is to limit the amount of feeds to a manageable amount and, very important, one needs to learn disregarding bloat without reading it in full or focusing his mind on it.That is the best filter one could have.
