querx hit it on the head. It's the internet. We're all throwaways. But Hubski has the ability to make you feel like you have a reputation, and that your reputation can be tarnished by saying something that may need to be said, but that you aren't comfortable associating your name with.
Adding in the twist of giving the reigns on a single throwaway account is very unique, because literally anyone can put on the same mask. It's exciting!
And either way, I've never been one to shy away from an experiment that might fail. Have you seen my poetry? Some of it is awful. But sometimes it makes something happen inside of people. So who cares about the experimental failures. Without them no one would experience the good ones.
