That's not the risk perspective I face, and I'd prefer to see Reddit accede to community demands (though I've long since abandoned much hope they'd do so, my own personal subreddit's been all but dormant for about five years on just that basis, though I've continued to mine it for links on topics I'd posted previously).
I'm not certain what Reddit's end game is should the IPO fail, or fizzle, but it would seem that preparing for an alternative online presence might well be a good idea.
