How about YC-rejected Alumni network?
https://news.ycombinator.com/item?id=10429290I filed 2016W at the very last minute, with no demo as "solo-founder". Actually I have a cofounder, just I never met him:) So my chance got rejected is much higher than 97%.
Today I can not stop thinking why not people got rejected start a network and help each other.
At least we could get feedback from each other, which we could not get from rejection.
Any thoughts?
