Originally I thought a bronze makes sense here. But in retrospect I do not. [...]
Introducing a bronze badge here is odd. Traditionally bronze badges are "welcome to the system" badges.
This made me think of another bronze badge introduced a few months back: Proofreader. It is also odd as a bronze badge because:
- It is certainly not a "welcome" badge, as you need to be fairly established already to have a shot at it (5k+ to access the edit queue).
- Reviewing 100 suggestions is not that easy a task, especially when compared to other bronze tasks, like "voting on a post" or "making an edit".
If we take the decision-making part out of the equation, it'd still involve finding 100 suggestions to vote on, and then reviewing them before someone else does. Maybe I'm just on the wrong site for this sort of thing, but having any suggested edits in the queue is rather uncommon. Personally, 100 took me about 3 months (and one guy who was really keen on editing tag wikis).
This might be less of a problem on SO, what with requiring 2-3 votes and having an insane amount of activity, but still.
TL;DR Proofreader should be made a silver badge, maybe with raised requirements.
