The Disqus system is cleaner and has much better spam control.A lot of you guys may have noticed that the site has recently fallen victim to a huge influx of spam comments. With apologies to readers who want to click links to buy fake Louis Vuitton purses and replica watches, we decided it was time to take action.  You’ll notice that we’ve installed the excellent (and amazingly, free) Disqus commenting system at the bottom of our posts, which should provide you with a better experience, and us with better tools to fight spam.

Unfortunately, this change effectively deletes all of our previous comments on every post, but this inconvenience is worth it for the fresh start.  Now go read some old articles and try it out :)
