It's a very bad effect, indeed!
I'd like to clarify why we don't use it -- it's not because we don't want to, it's because many (most?) of us (the active users currently) are living in PRC, where (already years) Google is banned. So, instead we use Bing, Yahoo, Baidu, Yandex and sometimes -- other SEs (Search engines).
It'll be interesting to read more opinions from scholars, scientists and other persons, who already are more familiar with
scholar.google.com (Google Scholar).
