Kinda makes you wonder why browsers don't have a built in (content based) deduping feature. I'm sure some users actually desire this behavior now that they're used to it.
Can anyone recommend a Firefox extension that can dedupe and clean your downloads for you?
This needs a (pdf) in the title, because it's a pdf file, not an web page.
I agree about the parent point of marking PDF as such but still feel compelled to point out that a 4 MB PDF is not significantly bigger than a lot of regular pages that are posted to HN.
In this very moment the currently highest ranked link, which is just a regular web page, on the HN front page had a total network payload of 3,937 KiB according to Google PageSpeed.
I sympathize with what you are saying though in general, and I think it is sad that so much mobile bandwidth is needed in order to read stuff.
The way that I personally get around this is that when I am on mobile I mostly restrict myself to reading HN comments instead of clicking through on any of the featured links themselves. But depending on how you like to use your phone I realize this might not be feasible to switch habit into.
I think most people do not do this on mobile. Even among the HN crowd. For example, on iPhone that I use, Safari does not support extensions. So for most people on mobile the site will download everything.
Almost all of my storage used on my phone other media are PDFs, but I can't split them up like I would on a PC e.g. I want to keep the textbooks and datasheets but I don't need every paper I've ever read.
