Limitations on the ability to edit my posts (aside from those in the Archive) would upset me, if not deeply, then at least significantly. IIRC, a time limit for edits was adopted at one point, but I'm very glad it was dropped.
Of course, I'm notorious for editing for a long time, and repeatedly, but see no reason why the mere fact that someone has replied to or quoted an earlier version is in and of itself a reason to stop.
However, to avoid confusion and annoyance, have taken to composing longer posts or those which I can foresee will take considerable thought and revision offline, then posting the result, but this doesn't guarantee that I won't edit it, only that it's less likely.
Anyway, also appreciate the opportunity to correct my posts when someone points out an error, or even suggests that it was unnecessarily harsh.
No offence, pacificquay, but consider the notion "to prevent things being changed once they've been replied to" kinda authoritarian. Also, it has the odour of turning discussions into games of "gotcha," which are, at best, puerile.
My (frequently edited ) two cents.
