I thought people who "clone them" was considered unethical? a copycat? And then if you start charging money from it, well, be read for the storm... I totally agree with the logic of the article. And I do hope this will become a cultural thing. I just don't believe it will be widely accepted because of ingrained "free and open spirit". I think, in practice, you'll be competing with fund-raising start-ups who provides free and better services with "free and open spirit" and lots of money ready to burn, after they took the large share of the market, small competitors will not be the only game in town, instead, they'll be out of the game. That said, it's amazing that pinboard.in is still alive after so many bookmarking services closed. I guess the philosophy of Don't Be a Free User could work well on specific areas.
