“after three weeks of development we decided to go for launch... we did some preparation and then we decide all right let's choose a day and put ourself like as a show this show got working and blow up to get to the front page what gave us thousands of engineers on the same day”

Ship after three weeks and hit Hacker News with a genuinely novel wedge

A strong wedge plus the right platform can substitute for months of slow organic growth.
