Why Google Scholar makes me roll my eyes

Here's part of the latest Google Scholar alert I received for scholarly articles on "Yellowstone National Park." Note the authors:


B. Bear, M. Lions, P. Safety, and E.E. Home (that is, the home page for the Encyclopedia of the Earth). Add the fact that none of those sites is "scholarly," unless you're writing a report for middle school. I still use Google Scholar for passive searches, or to look for particularly obscure citations. But as a discovery tool, they have a long way to go.
