Three years ago, September 18 2013 I posted a question in Area 51 exploring whether a 2nd attempt to launch an economics.se seemed to have a chance to succeed. It wasn't a site proposal proper, just an inquiry. A little later, Jason Nichols boldly created the actual proposal, and here we are today.
In that post, after presenting my approach as regards the scope that the site should have (discussing the possible reasons why the 1st attempt had failed), I ended up with a subtitle, which, a bit enhanced, appears to me to be much more accurate for the site we are actually have in our hands now, while leaving all options open, and so I put it forward as my proposal:
"For those who study, teach, research and apply economics and econometrics."
