Re:The Many New Possible Fronts (Score 1)

search engines that tailor themselves to the user

this could be the biggest pitfall

1. without elaborating much, privacy .
2. one might search for different domains at different times.
3. information cutoff. If i ever weighed something light, i'd remain forever in darkness.

Your suggestions of categorizing results according to search term meaning is already being taken, i saw few with clear distinction classified in google, but needs improvement.
