I use a text-only browser that has no suport for JS or CSS. I use it to read and comment on HN and to read every website submitted to HN. I have no idea what these websites look like in graphical browsers, but I can read 100% of them. I do not see fonts, images, layout, etc. I just read text and download files. For searching and downloading video from YouTube, I do not even use a text-only browser. I do everything from the command line. The only time I use a graphical browser that runs Javascript is for online shopping, banking and so forth. That is a very small percentage of overall internet use for me.
