Yes, but not necessarily the other way around. I'm not saying one is necessarily better than the other, but I think the 2 different UIs are serving 2 different goals. Focus requires commitment at some level, and I don't think most websites are predicated on the notion that the average user is committed, at least initially. Maybe once you make a sale to them and they get access to your product you can safely prioritize focus because you now have that commitment. I think engineers generally are above average on the skill of summoning focus, as you kind of need it in order to perform math, analysis, and logic.
