Hey there, I'm the developer of the app along with my wife, the author of the post. We quit our jobs over a year ago to work on a problem we care about and helping people connect to their goals through people is what we landed on. That being said, we spend most of our time on the tech! And I think your advice is spot on, that a portfolio of projects really is THE MOST IMPORTANT THING. It's where I would tell people to start. But from there, connecting people to others who care about that portfolio, is also important. I think a lot of technical people pay attention to the former, and tend to ignore the latter. Which is me too! So rather than "this is the only true way" I hope it comes across like a potential piece of the puzzle to some people.
Thanks for giving it some thought and for your perspectives, they really help.
