It's not about "Oh no, now I'll never get owner!!!11!1!1!!11!1!", It's more about moderation
I'm assumming that the mods of imgflip live in different time zones right? They can take care of the site anytime of the day since there is always a mod online while some sleep
Let's take msmg into thought: from what I see, we only have owners active when it's morning in America till like sunset in America (sure, we could change the owners up to fix this so we have an owner online when it's night in America, just in case a rule needs added or stream description needs updated, but I'm assuming you get the picture)
Having more owners could help out with having different owners online at different times of the day so that if something happens and an owner is needed, but all of the owners are offline, can do what they need to do
