I think you're in the minority. If there was a well known Reddit alternative at the moment, I could see Reddit having their Digg moment and losing a large part of the community. Subreddits could blackout and threaten to leave to the other website. That is something that would be taken seriously. Dozens of subreddits with 1-50 million users potentially jumping ship at once. If you had the right platform, with the right attributes and reputation, the stars would be perfectly aligned to take in a mass number of Reddit users. But, no one is in the right position to catch the ball at the moment (I don't claim it's an easy position to be in). It's actually unfortunate, because these moments don't come too often and I believe it allows Reddit to make these changes with little repercussions. Fans of old.reddit.com better watch out, I bet it's on the chopping block within the next year.
