Stack Overflow now accept anonymous edits

Glad to see it though, I use Stack Overflow way more than I use Quora.
It was infuriating to read poorly worded, badly spelt questions and not be able to do anything about it.
To prevent noise and friction, your change must be more than 6 characters
So, unfortunately, some of those infuriating typos will not be possible to fix. Reducing noise has benefits, but it also seems like these trivial errors are perfect for casual users to spot and fix. And it's possible that noise will actually be increased by people making spurious changes to cross the 6 character threshold.
People really will suggest very odd, highly subjective edits. I rejected one yesterday where a new-ish user wanted to add "Thanks" at the end of somebody else's question.
As I was able to make a contribution without even joining I just concluded that the complaining poster had somehow got it all wrong. I even got some sort of SO karma. There was no "moderation" in place either - my response (well two of them as I went back with some detailed and related info later) went straight onto the question "page".
It was also from somebody whose goal was apparently not so much to help as to get more reputation and the most highly-rated answer.
The main complaint, though, was with the inability to comment. Why add a separate answer when there's one there already that only needs a minor caveat or qualification? Not everybody who wants to contribute where they can is interested in collecting reputation points; comments require fifty rep and edits used to require 2K. Anonymous edits provides that sort of repless contribution opportunity (the rep points would go to the original contributor).
[edited for grammar, perhaps inadequately]
The guy complaining about SO seemed to be ignoring that he was capable of this as well (I think the implication was that it requires such speed that it's only practical for nutcases who hang out at SO all day), but he certainly could have done the same.
If you did suggest an edit, it didn't actually take effect immediately. It just looked like it did. You see your own edit as if it occurred, but nobody else does until the edit is approved by others.
