Just take it slow. Migrations tend to happen in waves, and we've got several more ahead of us even in the most ideal scenario for a Reddit exodus. The next pivot point will be at the end of the month when the bulk of account deletions will hit the server. From there it depends on peer pressure, how the quality of the site continues to decline, and how many more times /u/spez throws tantrums in the public media.

If you truly want to take your community with you, the best thing you can do is go cold turkey on Reddit yourself, regardless of whether you choose to self-delete or not. Deleting is better because it reduces temptation. From there, anyone who cares about timely updates from you will have to content themselves with waiting for others to repost, or they will need to follow you.
