Comment 47 for bug 80895

I'll offer argumentation in favor of allowing editing.

Argumentation

I argue that not allowing editing has these disadvantages

(i) forcing the author to leave markup (if the post allow markup), spelling and logic errors, and therefore a post that's not as clear as it could be, as permanent which is unsatisfactory

(ii) forcing unnecessary time to be spent on considering the content of a post before posting it, to avoid the dissatisfaction described.

(iii) making argumentation less easily accessible by forcing it to be divided among multiple post, for example a main argumentation and addition(s) to the argumentation, when it's realized that such additions are appropriate.

Supporting the soundness in the conclusion that allowing editing has a net benefit is that GitHub, a similar service to Launchpad and a popular service because of good judgment about many details, reach that conclusion. (And also goes further in allowing error correction by sometimes allowing editing of posts not authored by the user (compare with Stack Exchange and Wikipedia).)

The reason I raise an argument about this, rather than silently use the GitHub mirror instead (or create one if it doesn't exist), is that the introduction of bzr branches has made the net benefit of GitHub over Launchpad smaller so that this change in the web interface might make me use Launchpad instead of GitHub and save me the trouble of creating a GitHub mirror and post notifications of new GitHub discussions on Launchpad if the developer doesn't watch the GitHub mirror.
