In my opinion:
Take your career into your own hands. Email the company and find out what's up with your application status.
In my experience:
I interviewed for a similar position, and I emailed the company about a week ago. The response was something along the lines of 'Please be patient, we are sorry for the inconvenience.'
By the way, your email reads so much more nicely than mine did. I also plan to email the company again in two-ish weeks (like you said, to keep me fresh in their minds and let them know that I am very interested in the position). Any opinions on these two NLO hopefuls emailing companies for application status is appreciated.
