Is it possible to undo the current reverse-chronological order of the posts? Maybe I’m just an old stick-in-the-mud, but I preferred “forward in time” as the old forum (and most other forums IME) did.
Argument for newest-post first: the last post is often the “final answer” to a question posed *directly* above in the original post. Argument against: the last post can be the most irrelevant as people “spread the love” across the related topics to the initial post.
Either way I suppose it’s the same number of clicks. But there’s more “mental scrolling”, where you read from the top of a post to its bottom, then must scroll upward, searching for the head of the next (in time) post.
