I think the reddit blackout is good, I don't really like reddit as a website/company and if a lot of people feel strongly about it then I support it.

The problem is that unless you properly reroute the audience now, they will be gone forever. The reason why the CS kbin is so empty and slow is because I bet most people on the sub have no idea it exists. In order to find it, you need to go to the subreddit, read through a generic "reddit's api changes are bad" paragraph that everyone's seen a lot this month through to the end in order to even see the link. On new.reddit.com the kbin link is actually hidden behind a "read more" button. I bet loads of people have gone to the sub, seen a generic "We're still closed because..." message, and just clicked away without even seeing the kbin link.

Please make the link more prominent. Maybe reopen the sub but don't accept new posts, and pin a message saying "go to kbin for now". If you don't reroute them here then the audience will just go somewhere else and the kbin will die along with the subreddit.
