Forum:Conversations across two user talk pages

I'm curious: why do most "User talk" discussions take place on two pages simultaneously? E.g. Fred posts on Sally's talk page; instead of replying directly Sally posts her response on Fred's talk page; he responds again on hers (threading as a reply to his initial post), etc, etc. Is there a reason this emerged as a convention, rather than just keeping the discussion where it originated? It makes reading an entire conversation ...rather trying, when you might want to for reference. Starkidsoph ☎  01:23, 28 June 2023 (UTC)

Not sure if there is any actual reason why, but I find it very confusing to deal with. I also find it very telling that this is some random thing this Wiki made up as when you get Fandon employees use the talk pages on this Wiki, they don't do this bizarre practice (and the same is true across other Wikis. I'm all for changing it TBH. 01:27, 28 June 2023 (UTC)
 * Hell, I'm pretty sure at least one of our inactive admins refuses to do it. I think at least part of the reasoning is that if you respond on someone's talk they get a notification, so for a two person conversation it works better. Makes it harder to read stuff later, but during that conversation it makes sense. IMO the system is bad compared to having done it as conversations on a single talk page since the beginning, but it would be worse to change. Since people would be doing both for quite some time and it would be even harder to read for years, you'd have to figure out what was going on on the fly with each conversation. And in the future people would have to keep in mind that things change at a certain time point except they kinda don't and it's messy. Consistency is a benefit for these sorts of procedural communication things. Najawin ☎  02:45, 28 June 2023 (UTC)
