This article says nothing about the Berlin startup scene at all (except for a few vague, positive phrases). If you expect a description worthy of the word "journey", you'll be disappointed. It's mostly a self-congratulatory piece written by someone who apparently thinks that startups are some sort of hipster/fashion movement.
This is harsh. I read the comments here before reading the article and so found the article much less narcissistic than I was expecting. Fair enough, he does toot his own horn a bit but then it sounds like he's very much justified in doing so!
Those who went in expecting an exposé of the Berlin startup scene have misinterpreted the title of the article. It's clearly a personal piece written about a personal experience.
