Comment sections on today’s blogs and websites use antiquated technology. It’s all more or less the same stuff that has been done a decade ago, just with an emphasis on cloud services (see Disqus, IntenseDebate, etc). Livefyre offers a next-generation commenting platform. It also happens to be a cloud service, but that’s its least noteworthy aspect.
With Livefyre, comments feed into the page live with no refresh needed. The system is social: you follow friends and topics, and get notifications when interesting things happen across the web (e.g. “Your friend Julia has just commented on the article ‘The Internet Needs More Cats.’”). We also do things like keep track of every user’s reputation for automatic moderation, and drive traffic to other bloggers based on user interest. We want to shift website comments from being silo’d and disconnected, where hardly anyone knows who is leaving what comments and on what websites, towards a highly connected and social system, where website comments become as relevant to people as their Facebook news feed.
And yes, it is powered by XMPP.
