If you read through the issues people are having then you’ll see that it is not really to do with ergonomics or speed. Lets say someone is asking a multi-part technical question, as is often the case with this kind of subject, if I want to reply then I can’t see their original post, sure it is not a factor for people who just want to browse, but for anyone who wants to participate then it is a PITA.
With no-one answering questions, or posting, then a forum soon dies. When you make a forum that puts barriers in peoples way, then they won’t post.
