Decades ago, the author used to complain about the failure of online services to provide obvious and frequent feedback features. Whenever the user finished a search, there would be no inquiry as to the satisfaction in the search results -- no questions about the user's opinion of the adequacy of the coverage, the kindness of the interface, or the worth of the experience. Without any feedback mechanisms, no searcher would expect to get suggestions on what else to do. Of course, diligence in asking the searchers for their feedback would at least start discussions that could lead to improvements. And before those improvements arise, at least the vendor would give the impression of being a caring and hard-working servant to the public's interest.
