Are there any related stack exchanges we could establish mutually beneficial relationships with?
Or broadening the question, communities at large?
For other SE's, would a reciprocal goodwill campaign of having one of our members ask a "featured question" on their beta (i.e. one that we promote on our meta to our users) possibly incentivize them to support our beta?
I was thinking something along the lines of pairing with the History S.E. and asking a question about the historical significance of major economists or economic theories on their SE, in exchange, perhaps they could ask us something about the purchasing power parity of time separated currencies (i.e. 'Which would be more valuable, a Roman Denarius ca. 0 or an Italian Lira ca 1999 in terms of a standard basket of goods?' [though a redditor somewhere has probably already asked and answered that])
These certainly wouldn't be pushing the boundaries of modern economic science, though they would likely generate more views and members than 'purer' questions. Not wanting to debase the exchange too much, we could partner with one of the two Math exchanges, Cross Validated, or others for the more highly technical questions.
This definitely ties back to LateralFractal's answer on this question, but I wanted to narrow the focus to community relations.
We might also find other communities like Wikipedians or Redditors we could exchange imaginary internet popularity points with to benefit our respective communities. :)
(Sorry for the corny trade theory references, rereading Ricardo... :) Say what you will about factor inputs, dude could write. )
