In medicine, we're taught not to do a test unless it is going to change outcome. (You have a very high suspicion for a PE? Why do the ddimer? You're going to have to do a definitive test anyway.)
The same is true for applications. Asking friends and colleagues about their progress in the application process won't change how you proceed; you'll do your best at interviews whether your neighbor tells you he's already been called by ten institutions or not.
I would recommend avoiding asking others about their progress or checking websites in which applicants make claims about their successes. It's likely to make you nervous and won't change your management.
