I am curious as to why no one has built a web/mobile app to make this easier for the sellers.
also, there is no personal income tax or vat, so they can legally post whatever at any time and any quantity and put 100% of cash straight into the pocket - no need to formalize those transactions, no IRS hunting your instagramic wealth.
One of the things that I love most about software is how it might end up being used completely different than originally intended. When Kevin Systrom and his team started building Instagram, I bet that they didn't intend to provide a makeshift online marketplace for the people of Kuwait.
I posted about it here a few minutes ago but I got downvoted badly. No idea why.
