I'll start by pitching my own project:
WeAlly is a place where people can meet when they encounter an issue with a company. The issue can be as wide as complaining about the cost of repairing a Tesla tire, and as tight as proposing an improvement idea to a local business. Usually, you don't know who else in the world had an issue with the product or service he purchased.
The idea is to allow customers to declare themselves by "joining" a request towards a business, and to mark the request as solved when it is.
We will be able to see stats about how businesses are treating their customers in real time.
Let me know your thoughts, please. I'm launching soon.
