I saw this on usv.com today:
Popular Science has decided to turn off comments. They aren’t the first and they won’t be the last.
As Adrian says in the usv comments:
Let’s face it – dropping comments on PopSci isn’t going to stifle societal debate. There are more than enough places online to debate the impacts of science.
There are so many places on the web to talk about stuff. There are the blog communities, like AVC and many others, and there are the link sharing communities like Reddit, Hacker News, and USV.com.
The web (and increasibly mobile) is a great place to talk about stuff that matters to you. It always has been and it always will be. Some publishers will foster those conversations on their own domains. Some will let the conversations happen elsewhere. I am not particularly concerned about who does what.
I am concerned that we keep talking and I am not the least bit worried that we will continue to do that.
