User blog comment:Poseidon133/Why do some wikis have talk pages?/@comment-4568327-20150419224534

As a Wikipedia editor myself, I personally prefer user talk pages over message walls, largely for the reason that it is a lot easier to leave messages to users, especially warnings for users that vandalize articles. Wikipedia has a pretty well-set system for warning users. Message walls are a bit more messy, since I'm not sure how to organize warnings. Wikipedia organizes warnings by month, but the message wall looks confusing and disorganized if I use that system of messaging.

Also, talk pages are very easy to archive and transfer, unlike a message wall. You'll lose message wall messages if your wiki disables the Message Wall extension (wish there was a script that could copy all those messages into talk page format so wikis can actually turn back!), so that's an unfortunate trap.
