So I've integrated Disqus into the site. Yay! It allows people to log in using facebook, twitter, openid or Disqus' own user authentication system. Or even guests (I'll see how this goes, I hate spam). It also has a very slick moderation / admin system and by being externally hosted it fits into my basic goal here on the lifestream; for it to be as portable to a new webhost as possible.
