I’ve noticed Facebook’s search has started catering to the lowest common denominator as well. Searching for (made-up example) “Louis Potter” used to give all exact matches priority. Current results look something like 1) Louis Potter 2) Luis Porter 3) Louis Potters 4) Louis Potter (#2). I don’t like when search engines assume that I’m misspelling words/names, and it would be nice if they adapted for individual behavior in this regard.
