The interface we're given to try to mine this data is a keyword search, with modifiers. This is great if you're looking for the most popular use of a word, but if you're looking for the unpopular, you're screwed.
People tend to use the words they already seen used to describe a concept or viewpoint, or meme. Over time, because of our heavy use of keyword searches, the meme tends to monopolize certain keywords. This leads to the exclusion of other memes that discuss the same subject.
Keyword search then tends to result in an echo chamber, where a majority viewpoint gets found first, and much more frequently. It's a popularity contest if you will, for ownership of the keywords.
Language gets used as a tool of thought control if you think about it long enough. If you can invent a neologism, and maintain control over it's definition, you've just bought part of the language... now that's power!

There are alternatives, conversation unmediated by machine is the best. If you give authority to the machine, you end up thinking like one. Do not go gentle into that good night.
