The first comment on this makes me nostalgic for the era when Google et al(tavista) weren't aggressively pruning and ranking results in order to give the "most efficient" results for a given query. There was actually a chance that your question would lead you to a small, active blog with a thriving microcosm encapsulated by a "blogroll". Nowadays, you mostly get a platform like Reddit or Quora, where the QC is handled by an aggregate[0]. Interactions feel much shallower these days too -- but maybe that depends on where you go.<p>[0] <a href="https://en.wikipedia.org/wiki/Wisdom_of_the_crowd" rel="nofollow">https://en.wikipedia.org/wiki/Wisdom_of_the_crowd</a>
