comments

After seeing Disqus being used by Rob Loach I thought I would install it.

So what is Disqus?
Well it is basically a centralised commenting system. All Disqus enabled sites allow commenting, the comments are then stored with Disqus. If an author of the comment is a Disqus user their comment is affiliated to their account. Disqus users can specify friends and comments can be followed much like twitter posts are followed.
