Seth Dixon‘s insight:

This is a real island…well, sort of.  It is an island off the coast of Thailand (most certainly not Ireland), but there is no castle on the top.  Photoshopping and easy file sharing make it harder to assess the validity of online resources.  Most students start their research with online sources.  This isn’t to pretend that that I’ve never mistakenly assumed that some online content was accurate when it wasn’t true; I think we all have.  I think that it’s important to conversation to have with our students so they can be more critical consumers of online information and use some geographic skills to assess the quality of that information.
