Personally I'm ambivalent. I don't think it's especially useful and nor is it especially harmful to he particular questions.

Where I do have an irritation is them being pushed en masse to the front page by the way that the review system works.

When a single player goes on an editing spree it is relatively easy to point them at [this][1] or something similar and slow them down. 

Unfortunately the current issue is that the second reviewer is effectively pushing them all to the front page. Orchestrating a number of reviewers to only push a few will be near impossible. 

I think he solution is to try and get SE/SO to change the way that edits approved in a short space of time are pushed to the front page e.g. batch them over several hours. That though seems like an exercise in waiting for hell to freeze over.
