I think the thought about FB is more about distribution to a 2 Billion potential users and less about the very centralized aspect of it. I'm sure it will launch on Telegram as well.
We have developed this app so people will be free to offload their day to day stress without being judged by their friends for being complaining too much.
It's also a great tool to show brands your dissatisfaction with their services or products. Hopefully, it will make them to fix up the problems and everybody will win from it.
Essentially we are like a feedback box for everything!
Please Let us know what do you think(For good or for bad!), we appreciate all feedback and will try to address it.
