For what it's worth, I'm the editor who was referred to in the question.
I derive a real sense of satisfaction from editing questions and answers on the sites, and flagging anything that falls outside of what generally makes 'good content'. Sometimes those edits are significant and almost a complete rewrite, other times they are minor but may help with categorisation or search engine ranking.
My editing spans across recent additions to the site, anything found on the various review pages, and occasionally searches. My intention is not to flood the site with as many edits as possible, but to improve things whenever I see them to help improve the site overall. For example, I might come across a user's first question that needs rewriting, and in the process discover that a lot of answers to that question could do with some editing as well. Once I've finished that might result in say, 6 edits.
I can understand concerns about the front page being flooded with question/answer revisions, but I never actively think about it when I'm editing - especially when I imagine other traffic will push my edits down the front page anyway. For new questions there is also the QuestionsQuestions view which doesn't include edits anyway.
I would be quite disappointed if any measures were taken to slow down the editing, because it would turn it from something I can easily do in a casual way to something I would have to actively think about - and I don't really have any desire to do that.
My preference would be for an option to remove edits from having any impact on the front page activity.
EDIT: Something clearly needs to be sorted for this. Today I was piling my way through reuploading images not hosted on i.sstatic.net - since I've seen a number of questions lately with broken images. Call it preventative action! However a few members complained in chat and asked me to stop editing, so I have for now.
