The requirement for having the review link appear in the top menu newly got raised from 200 reputation to 1000 reputation. This makes sense in that experienced users rather than inexperienced users should be encouraged to review.
But there are cases where the requirement doesn't make sense because the relevant experience is not solely reflected by the amount of reputation. A user who has achieved a high flag weight but has less than 1000 reputation should also be experienced enough to be encouraged to review. So, I suggest that the review link should appear in the top menu not only for anyone with at least 1000 reputation but also for anyone with the Deputy badge, i.e. anyone who has achieved a flag weight of 500 (which should mean that they know how to review and flag appropriately).
One might wonder how many users with less than 1000 reputation that has the Deputy badge. This can be inquired by using the Data Explorer. Here's the result for some sites:
- Stack Overflow: 89
- Server Fault: 6
- Programmers: 2
- Super User: 1
- English: 1
- Ask Ubuntu: 1
Even if these are not great numbers it makes sense to encourage these users to review because them having the Deputy badge implies that know how to review and flag appropriately and, thus, they should be encourage to review because helps improve the quality of sites.
