I find it astonishing how much of my laptops resources are occupied by a web browser. But I came to believe that it was not necessarily a problem with the web browsers per se but that each website would have a variety of javascript constantly running, and most of that code is not providing any information that I want. So I have turned off javascript in the browser. It breaks many sites, but, especially for news sites, it makes for a quieter experience.
I also like to archive many of the articles that I read, but I don't like keeping bookmarks. So I wrote a small utility to convert html to text by combining 'readability' (python) and lynx (text-base web browser), which does a nice job of formatting the content and storing the hyperlinks as footnotes. This archive is also nice and easy to index if you are so inclined.
