I think it's shallow and not because it's short. To me, it just sounds very typical: "I joined Google back when it was fun. Now it's more bureaucratic and less fun. But I made a ton of money on the stock." I think there have been countless blog posts from Ex-Googlers like this. It's fairly shallow.
And it is worth noting that a lot of the bullet point lists do start with "I made a ton of money" in as many words, which is also just not very interesting to most folks, though it is certainly very relevant and important to the writer.
