Well why a hustle.. I figured out it was a business... the business owners can price it however they want.
For 50USD a month you get the possibility to increase your network with a number of legit people in the business.
Co-branding that should enable you to price your own merchandise higher.
Some traffic if you had nothing previously going.
Procided you have good materials, it means a higher chance to get it going soemwhere.
Decreased competition in terms of quantity (till the moment when it will get quite saturated but people who are just not good enough get repelled by the fee after a while)
That's the unique selling proposition other websites don't have.
SO it's cool.
And yeah, some of the people are also available via twitter... Now what is there priority, something screened a little or random submissions...
PMP makes sense at least on paper. The pricing is also just about right.
