By design or otherwise, you seem to be squeezing the BoingBoing discussion forum into a shape that’s substantively different than what it was before. Some of the protections you list above seem better-suited to a forum aimed at 12-year-old videogamers or some similar unruly gang of reprobates. To the extent that the BB discussion punchbowl has been pissed in by foulmouthed clods, ad hominem attacks, or other standards-defying acts of ungallantry (which, compared to the cesspool that is the internet as a whole, is a relatively minor extent), I don’t believe it ever required a particularly firm policing hand by the mods.
In all the examples you cite above, having the edits visible to mods (yet invisible to the common users, except the indication that a given post has been edited in some way) serves the same purpose. If someone flags a naughty post, even if the offender hurriedly changes it before the mod sees it, then the mod can still see the edit (though the rest of us can’t), and tender whatever admonishment is necessary. If nobody sees the offending post before it’s changed, then nobody flags it, nobody’s offended, and no mod action is necessary. And as for tracking changes to event dates and such, that’s wholly unnecessary. If somebody needs to edit the date or time or venue or other circumstances of some event, they’ll no doubt label their updated post as “UPDATED!!” Who would need to know when the event used to be scheduled for?
In my experience, people’s behavior is always more civil when they know their peers can see them.
That doesn’t follow in these circumstances. It’s a public discussion; people already know that whatever they post is visible to everyone. If they feel like posting something actionable, are they really going to refrain because, if they stop and think, they’ll realize that somebody out there might actually read what they wrote? Wasn’t that the point?
Now that paragraph I just wrote is relevant to intended comments, that is, ones that say what the commenter actually intends to say (whether constructive or destructive) without typos or other errors that the commenter later wants to fix. The other comments, the ones with mistakes or that end up requiring further clarification or other adjustment, may not be actually representative of what the commenter was trying to say. As we leave our mark on the wall of the digital society, we want that mark to accurately represent our voice insofar as we are able. The comments form at, say, KNAC.com does not allow commenters to edit their comments at all, which is annoying to a relatively mature commenter (as I flatter myself to be), but it’s also just as well: it’s KNAC.com, a website devoted to the music played by a long-defunct Los Angeles area heavy metal radio station, and the quality of the discussion there is… well, I don’t really bother to read or post there much, and I’m a huge Iron Maiden fan. The site probably shouldn’t have comments at all, since the discussions get obnoxious and sexist (though surprisingly rarely racist) pretty quickly, and insults and invective fly back and forth all the livelong day. But BoingBoing is a very different place. Since we are rightly permitted to edit our comments, we can tuck in our shirts and straighten our ties and wipe away the boogers and, if desired, modify our positions in our posts.
Yes, anyone can take a screenshot or view a previously-cached page to view a pre-edit comment. Well, almost anyone. I can’t. I honestly don’t know how, short of photographing my screen with an actual camera before somebody edits something. But having a permanent record (just one click away) of all the times I left out a preposition or misspelled February or even belatedly realized I was mistakenly upbraiding the wrong person for saying something that he or she didn’t actually mean? That strikes me as a simple case of The Powers That Be looking over my shoulder and saying, “Watch what you write. We’re keeping an eye on you.” It feels weirdly like being tracked by our browsers and ISPs; it’s just a few bytes of more data to be potentially used against us.
You guys run this place; it’s your space, not mine. You can moderate it all you want, and I fully expect mods to be able to keep an eye on such things, largely because as a condition of using this forum, I have to submit to the idea that the mods know all and can act with relative impunity regarding my presence here. And I have to trust them not to abuse this power, and I have no problem doing so. But giving full and easy access to the edit history to everyone else around here is creepy. It assumes that we’re all potentially bad apples who might abuse the system, and it expects users to keep a suspicious eye on each other, and the idea that “if you’re doing nothing wrong then you have nothing to hide” should be self-evidently sinister.
when you post something to the Internet, it is naive to expect it to be permanently redactable. So why not embrace that rather than pretending otherwise?
Just because Google and the NSA have instant easy access to everything I’ve ever done on the internet down to the last keystroke does not mean a place like BoingBoing should “embrace it.”
