A thread by Nikita Bier :
Nikita Bier made his success by selling his social apps like Gas (to Discord) and TBH (to Facebook). I could go ahead and quote the entire thread but instead go to twitter and give it a read. Its one of the best threads I have read in years and is a delight to read for any Product Manager or an Entrepreneur.
If you have read Disciplined Entrepreneurship by Bill Aulet - this thread comes very close to the lessons he gives in his book.
