I'm new at this, but one thing that I think you should try is--every three months or so, open up your personal and account profiles, and try to find something to change about them. If nothing in your life has changed, you can always twiddle with the 'request e-mail section'--change the distance back and forth.
And, do they really not have anything for you, for months at a time, or is it just not things that you like for months at a time? If you try out a hamburger every three months or so, I'd bet that you'd stay active.
