Quick test of new comments system (using DISQUS)

Just testing a new commenting system - Disqus.

Looks like it works OK so I'll keep it online for now. Currently, you no longer need to be logged in (previously you needed to present either a Blogger, Google or OpenID credential to comment because of spam) since Disqus is supposed to handle this better. However, if the spam starts to reappear, I'll have to restrict it again. For blog authors, check out Psolonoid as well. It provides an easy and controlable way of creating links (like trackbacks) between blog entries.
