I'd like to submit two posts:
A short Op-Ed: Why Cashless is Bad
-and-
The “Flippening” - Fact of Fiction? I’m going with Fiction...
They are both a bit short and the first one might not be the kind of niche you are looking for, but I thought I might as well share them.
They seem long enough; we won't be able to include entire huge articles anyways so this looks like the right size, cheers.
