An unconditional **Yes**.

We are seeing significantly more editing and improved voting.

The new "close" tab in `/review` also increased the amount of closing. And we are seeing more bad content get deleted.

I also had some more stats about review at: http://meta.stackexchange.com/questions/111941/is-the-marked-state-for-reviewed-questions-bleeding-across-to-late-answers/112198#comment291458_112198 

The increase answer deletion does directly correlate with us catching more spam and bad answers. 

We are seeing close to **4000** reviews a day all by users that have `Strunk & White`.

Bottom line, content is getting more improvements, people are participating more in janitorial work. Only big pain point is that we need a few more mods on SO, something that will be solved by the election.
