User blog comment:Poseidon133/Why do some wikis have talk pages?/@comment-1038387-20150415102423

Talk pages are the standard. They've been around since the dawn of wikis (or pretty close to it). Same story for User talk.

User talk had the downside of only giving notifications on your own user talk, making conversations either tricky to follow or ping-ponging, neither of which imho are beneficial. Many people still prefer this, though. I prefer Walls.

As for talk page vs comments, I stand firmly with talk pages. I'm an old-fashioned guy - talk pages are to discuss the page, not the subject of the page. And with comments, you get more "omg i liek [Character]" than with talk pages. Discussions and conversations are easier, as it's clearer to see who replies to whom.
