I'm always wary they'll use one of these "improvements" (some people may find this useful, I just see it as useless fluff) as justification for killing old.reddit.com. But perhaps that will be the kick I need to finally give up reddit for good.
New Reddit is so slow it brings even an i7 to its knees. It really needs some optimisation. I didn't look at the code but it seems like their pulling in so many frameworks..
Until they fix this I really hope they won't get rid of the old.reddit.com option :(
I prefer the old layout too of course, though I suspect I'm in the minority (though not within the group of HN users of course!)
I wonder what are the technical requirements for this kind of real-time user feedback/interaction with the server(s), what kind of infrastructure handles this kind of load, and how it's justified internally considering this (I assume) is new infra and code to maintain, scale, and pay for.
