It shouldn't be totally dismissed, but GlassDoor suffers from the same disease of all review systems: a pissed off engineer is far more likely to write a negative review to warn others and/or stick it to their former employer than a happy one would think to go and write a positive review. (For a sample size of one: I'm happy at my current employer and couldn't possibly be bothered to go put a rating for them on glassdoor. Moreover I find sites like that are often more in the parasitic class of the internet anyways, so not sure I want to donate my time and information to help them prosper in the first place.) You're slightly better off than with a random internet poll in that the pollee is at least claiming to have first hand information on the subject they're answering questions about, but it's still hopelessly biased and you shouldn't even try to reason about trends or comparisons from that data. Better to take individual statements from the testimonies on there (with a huge grain of salt) and leave it at that.

  GlassDoor shuts off your access to the site if you don't provide it a review and salary information. (Unless you're a cheater and pretend to have come across it through a Google search, like myself.) In this way, it is less likely that GlassDoor experiences this problem compared to the average review system; anyone who uses it must participate, not just angry people.
