First: I’m going to assume that “shouty shout” refers to you trying to convey the idea that your shouting and are passionate about what you are saying. (as the other interpretation does not make any sense)
I had not thought about email only users and was not considering them at the time.
So the question is, is updating the original post really a problem for email users?
I mostly just summarized the information that other people had sent to the channel. So the email users should already have been exposed to this information from when that person commented on it.
