Usually, not always, the comments have a strong counter argument against all or parts of the original article. If you don't skim through them to at least see what people are saying, you're setting yourself up to be spoon fed someone's agenda.
That's rarely true for the vast majority of the internet, or if it is, it's buried fucking deep down in there. Reddit can sometimes make the exception, same with Hubski. From my purely subjective experience - which is the best I can offer - comments on sites that AREN'T heavy on the comment sections (i.e. article comments, youtube comments) are usually a lengthy, cliche libertarian follow up to something by and large unrelated, blatant racism, or just "wow I totally get that joke! lol" I tend to avoid the comments. I'm not these people's friends. I don't give a hot fuck what they think about the issue at hand or their opinion on anything from what I'm wearing to the latest political turmoil in the Middle East. Do what people should have been doing this whole time; read the article and think about it critically on your own. Also be sure to follow this maxim when reading about any advance in technology; if it seems too good to be true, it probably is.
