Nice theory, but it's Google degrading. They actually removed features for more accurate searching. Or they arbitrarily ignore them--all the people in this thread saying that "word" now functions like +word used to, are mistaken (or didn't use it much in the past decade) because often it does not.
And you didn't even need to use +word for most words, because it would only give you results that hit all the keywords in the query. You only needed the + operator to include "stop words", a relatively short list of common words that Google would filter out.
Also, given that personal webpages are way less popular than they used to, the Internet might not even be growing that fast, at least not the parts that contain the type of random useful info that we used to be searching for. They can't index Facebook (not very deep), or most of the popular mainstream services that people write their thoughts into.
