Bumping this one because I think it's worth adding. (I wouldn't have spent time working on it, otherwise.)
I mean, I know it won't
stop people from multi-posting, but, I think it'll likely attenuate it.
I was reading theymos' proposed
welcome message [1], and this part jumped out at me:
Multi-posting: Do not post twice in a row in a topic. Instead, edit your old post.
The fact that multi-posting is one of the three rule violations theymos thought important enough to include in a welcome message suggests to me that this patch would add value (I'm not going to re-iterate my own rationale, that's already in the OP).
[1] Off-topic, but, I'm not sure why that welcome message was never implemented: typos aside (a missing period, "sucessful" -> "successful"), I think theymos
nailed it. It's a
great welcome message, FFS. I think sometimes the community shoots itself in the foot by nitpicking things to death. I mean, is that the absolutely most perfect welcome message? Probably not, but, I don't think I could do any better, and weighed against the ~6 years of new members that
could have been reading that upon joining, instead of nothing at all, I mean, just, holy shit... talk about a stupid trade-off.
