Could not disagree more strenuously.
If HN wanted to do the color thing to indicate depth I would also be ok with it, but the collapse feature is one of the nicest things HN has introduced in years and saves me tons of scrolling.
I'm not talking about comment collapsing which is essential but about story hiding on the front page.
Ah, apologies.
I still like that though :)
Why?
Because there are often stories which sit at the top of the page for extremely long periods which are not interesting, its a was to paginate the information off the front page which I find boring.
I couldn't agree more. I had switched over to hn.premii.com for mobile browsing solely for the ability to collapse comments, and only recently discovered its addition here.
