Yes, this is my recommendation. Community is a years project, not a months project. So once we have resolved the major blocking stuff per Tom, and have a rough design that’s not too objectionable to too many people, giving people some time to absorb the existing changes is a good idea before getting too many wedged in at the last minute.
Also: likes are on now? Is that kosher @tomchick?
Choosing “themes” per user is an option, but it will take us a while to build that. My definition of “a while” is roughly 6-8 months, but don’t hold me to that. Just a rough estimate.
