With no ill assumption and no aggression intended: what is your business model and idea of giving back to the communities you are distilling the value from? And how much did you think about the incentives this would place on spammer and SEO artists to pollute your data source?
The way we use it in our apps is to take a pool of identified experts for a search query, augment it with relevant news from other sites about the topic, sprinkle a little bit of quantitative KPI data over it, calculate various NLP scores, and then shake it well and voila, you get a nice aggregate of socially validated data.
Works well and it reduces the noise significantly.
