When giving detailed answers like this, it is very easily possible to produce more than 10 edits. And this, without any disputes or other contradictory interaction with other users. In that particular answer, I was then informed of this 10 edits rule ; and thus stopped editing.
(I did already try to suggest means to reduce edits by having a better preview like this, but at that time was unaware of this 10 edits rule at all.)
So here is my suggestion: Currently revisions are directly numbered. Minor revisions of the same user (like, a couple of characters or similar) might be numbered differently. Thus 1 1.1 1.2 etc.
Edit (ha! Also here!): Better suggestions: Minor revisions by the same users should be directly marked by the user as such. In this manner, artificial "noise" for the "active"-category is avoided.
Next edit/suggestion: Writers simply mark a minor edit with
m in the "Edit Summary". In this manner, unintentional abuse is minimized (no suggestive checkbox). (I am very reluctant to the current approach to contact moderators ; not everybody is in meta-talk-mood)
