But Reddit at levels 1-5 is almost indistinguishable from HN at levels 1-5. The only differences between HN and Reddit are topic diversity, collapsing, and limiting comment display to the top 100 or 500 comments.
That has me using HN less in recent months. It failed to account for the inevitable with display tools, so a thread that would be perfectly navigable on Reddit is unreadable on HN.
Well, after reading the comments in this thread here, and some of the comments over on Google+, I'm gonna have to say you got that prediction wrong. =)
Facebook, twitter, stackoverflow, et. al. have all previously used the constantly-updating stream technique only to switch away to the "x new posts, click to view"
That is unusable.
~ Because the pause button is light gray on white.
~ Because scrolling down the page, which in almost every other scrolling interface prevents any updates from affecting your scroll position (terminal, chat, twitter, etc.) didn't help.
~ Because the page just moves in weird, small jumps and feels like it's broken not like new content is rolling in. (They're actually accounting for huge jumps! and chose instead of move it in tiny glitches...)
The button is black text on light grey background, yes. I think the parent poster is more pointing out that the light-grey-on-white-background, which isn't very noticeable.
(I didn't know there was a pause button until read this thread.)
