Can I get a brief summary from a fellow HNer, not too versed with reddit and reading all the many reddit comments have confused me more than just simply reading that man's confession.

This is one of those times if you want to find out the truth, just step back and wait a while. It's all over the place in that thread right now.
He has used his stolen fame for good, however, by instructing his followers to donate to a charity concerned with clean water initiatives. He has motivated and inspired many people to make changes in their lives (including, but not limited to, becoming successful app developers themselves). Meanwhile, he's just an average joe who faked his way to the top.
My $0.02: if it's true that he is indeed a phony confessing to the world (which has yet to be confirmed), good on him. He has become what he originally faked. Maybe he isn't a successful app developer like he pretended to be, but he is a successful community figure no matter how small his circle may be. He has motivated, inspired, and helped the people he duped into believing his story. If this is all true, I've never seen a better use of being a conman (and probably never will). He's happy for the people he's inspired to become successful which seems to have made him genuinely happy himself. But, who knows, maybe the hoax is a hoax and we're the ones being duped.
