Consider using this Adblock/uBlock filter:

    news.ycombinator.com##td.subtext

I've been using it for a week or two now. It blocks links to all comments (besides Ask HN, Show HN, etc - which is why I'm here). I've drastically cut down my HN time but still keep up to date on tech news. I also read the articles in full a lot more than I used to.

(It also tidies up the homepage and makes it look a lot cleaner, IMO: http://i.imgur.com/RzHKD2d.png)
