Will you build a competitor? Move to one of the existing alternatives?
I've received so many messages of kind people offering to work with me to build a competitor to Reddit, and while I'm very flattered, that's not something I'm interested in doing. I'm a product guy, I like building fun apps for people to use, and I'm just not personally interested in something more managerial.
These last several months have also been incredibly exhausting and mentally draining, I don't have it in me to engage in something so enormous.
I don't think he will. He'll probably avoid investing effort into apps that are reliant on a third-party service now after how he was treated by Reddit.
I've definitely been in that position where you put your heart and soul in to a project, and then it gets ripped away from you by forces beyond your control. It sucks, and it can really kill your joy for that kind of thing. I doubt he's going to want to get involved in another social network, and it sounds like he already has a new project he's excited about.
