Thanks for the concrete example of Sims. That's consistent with what I know about the job market - a good letter can get you an interview but not a job. So maybe the guy who made that critique knew about Sims and generalized from there or maybe there are more examples.
... which is why I made this new account. As long as I'm anonymous, though, people's defensiveness is really helpful. It got this thread a lot of attention and led to some really well-constructed rebuttals of those concerns. I'm sorry (kind of) for pissing people off, but I didn't make up those rumors and it's better to air them out then to let people assume they're true.
