Don't let the trash talking ensue, its completely unnecessary.
One point I would like to make though, is that the people on here seem to be the more motivated and among the more highly qualified applicants than the rest of the fleet. Of the packages that went in front of the board from my command, I personally know all but three of the applicants, and most of them couldn't care less about whether they got accepted. They put in a package for one reason or another, but don't really have their heart and souls into it like we do here.
You also have to realize that while the program as a whole has an inordinately low acceptance rate, specific programs differ. For example, medical corps has an extremely low quota and a handful of applicants, so the selection rate there will be low. Nuke on the other hand, has a decently sized quota and a limited number of applicants (Personnel are only eligible if they are at one of the three training commands) so the rate there is higher. So yes, it has a low acceptance rate, but you'd have to be a fool to gauge your chances based on the overall number instead of the numbers for your intended designator.
