Tagging requires mental energy and some level of abstraction prowess - and might still be misleading. Social media is geared towards making the user expend as little mental energy as possible - and then organize the information they provide anyway for the advertisers using behavioral patterns or some variant of AI. This is probably considered by the industry to provide more reliable information - its like the difference between asking people to explain ethical behavior compared to recording what people actually do in reality. So, we have a "tagging" model driven by advertising needs, that discourages our own need to tag (intellectually categorize) the content we consume. Instead of moving forwards, towards a more accurate tagging system that supports reflection and concept organization, it seems to me (in my pessimistic moments) that we are moving backwards into an online world where the only ones that know what we are doing are the machines.
