User blog comment:Toughpigs/Wikia's new Forum demo/@comment-1474707-20120911115829

The big problem with this new forum, and also message wall, to me:

a) The way it appears in recentchanges and wikiactivity makes it really hard to distinguish between forum posts and message wall posts. That's why there's a big prefix like user talk: or forum: which has been got rid of.

b) With large threads where lots of people post regularly, with the old system all you do is click "diff" and can see what has been added to the discussion instantly. With this - you get taken to the top of the discussion and have to scroll all the way down to the bottom. This is very time consuming for popular, large threads.
