I'm in my town's local Buy Nothing group on Facebook, and it works alright, but if I ever get rich enough to go full-time on a money-losing business, I'd love to build a dedicated app to replace the facebook groups and make the process easier for everyone. The current system is incredibly clunky and ripe for abuse. Here's what it looks like for me: 1. Post the item I want to give away 2. Check back in a few hours to see if anyone has commented to say they want it (I'd do first-come, first serve, but it gets abused by people who watch all day and claim everything) 3. Go through the replies to see which are actual requests and not "my friend Steve would probably be interested!" 4. Generate a random number generator and take the result mod number of legitimate requests 5. Notify the winner and give them pickup instructions 6. Put the item out for them About half the time, there are issues. They don't see the PM I sent them, they forget to pick it up, they realize they have no means to pick it up because they have no car, etc. Issues with this system: * Many parts to the process where I have to do something, wait, then come back and do the next step hours later. * No reputation system. Recipients who are flakey or unreliable can continue being flakey to lots of people, wasting the time of givers, making the whole process less appealing. * The gift givers are expected to choose a winner at their own discretion, but people are likely choosing recipients based on unfair biases. Here's how I want it to work: 1. I put the item on my porch 2. I post an item I want to give away. At the time I post, I specify the parameters of how to pick the winner automatically (e.g., they have a rating >= X, they have a verified address within Y miles, randomly select after Z hours). 3. The system automatically notifies the winner and sends them pickup instructions. 4. The winner comes and picks up the item. 5. We both leave feedback to say the transaction went smoothly.
