I've been reading a bit about Stack Exchange's site model recently, and this answer led me to study up on what graduating means. Specifically, I noticed that the reputation thresholds for privilege levels are higher on graduated sites than this site. The main meta confirms this.
Since privileges aren't grandfathered in when the site graduates, there might be a few users with less than 2000 reputation who review suggested edits/low quality posts now, but will lose that ability once the site graduates, as well as people with less than 10,000 reputation who use the moderator tools now to look for spam or view deleted questions, but will lose that privilege when the site graduates.
Assuming the site gets more attention once it graduates and assuming this attention is coupled with more suggested edits, more spam, etc. could this create a problem? I think the moderators/high-rep users are doing a great job at the moment, but I saw the possibility of more work being put on fewer people so I thought I'd bring it up.
Maybe it just means that instead of x minutes between reviews, there will be 2x minutes between them, and maybe more attention will bring more users to help with these tasks. In those cases, there won't be a problem, I don't think.
