This feature should have the option to be disabled but by default should be on for the new SR users.
It should be off by default. Like with any user interface, anything that confuses people is inappropriate. I've read a few posts where people thought that there were bugs with the site and didn't know if it was working properly or not. See the titles of posts like "flashing screens", "sr not loading properly", "can't browse pages", etc. Those are all related to this. As far as user interface design goes, that's the worst possible thing that can happen, that people can not figure out how to navigate the site.
If it is made to be optional there should be no objection from those who don't like it, right?
Of course if it was an option that you set in your profile, no one would complain about it. Then, if I was going to post about it, the title of my post would have been something like "Proper User Interface Design". I don't want to post about this at all. I don't feel like I should have to. This is basically free consulting. Like I said in a previous post, there's a reason that web developers universally do not use these properties this way.
