Don't underestimate the power of disgruntled users. There is no place right now that can handle Reddit - all the alternatives that aren't monolithic corporations can't handle the traffic. Kbin included. So the best anybody can do right now is be on the lookout. This isn't like it was when people left Digg for Reddit almost two decades ago. It takes quite a bit of resources to manage a large migration - it will be in small steps, but rest assured.... Reddit's mods and their communities now are forever changed....
As a mod of some reddits that will go back online, we're now going to be actively promoting alternative sites to also post content on and congregate - we have to do it piecemeal because of the technical requirements. We'll also be expanding the topic of our subs to include any news that's critical of reddit proper and these issues, so we won't let things die.
