The only problem with that is that they'd have no idea the data would be bad. Even if they did, there's nothing stopping the marketers from taking the bad data as proof one or the other campaign was actually working.
One thing I noticed was there Hamburger menu in the top left hand corner. It gives me, a web developer, a chuckle to see the hamburger menu as an actual hamburger...
But regular users will have no idea what to do with that icon. Just a small example of the redesign I took away from it.
I think JS rendering can definitely be a major issue, too. Uber (I know Uber is bad, but m.uber.com is a great piece of engineering) and Netflix have taken big leaps in rendering performance, they'd be wise to take a page or two away from them.
Serious question: Why do you think m.uber.com is a great piece of engineering? I've tried it on 3 phones, with 3 different browsers, and I've never gotten it to work at all. I'm not saying that your experience is invalid or anything, just that my impression is the opposite of yours, and I'm wondering why.
Slightly less chuckling:
1. the menu appears as the page loads, and then pops out of view.
2. just loading the crucial bits takes 7 seconds, and that's on an off day with a fancy fast internet connection in one of the richest countries in the world (Netherlands).
I'm generally less negative than others about style changes, but i loathe how heavy the whole thing feels. The fact that it's not taking into account accessibility at all (so far) is also problematic.
For 'old' reddit I used RES and often disliked how clunky it made everything. But its features were generally worth it. I do not see what benefits the redesign offers that is worth the 'heaviness' of the whole thing.
