I’ve switched the blog comments back to Disqus. They’re track record of innovation cannot be ignored and they are definitely worth a shot if you’re looking to build a solid online community.
In an a post I wrote called How to: Build a Vibrant Community of Blog Commenters one of the points I made was “keeping it simple”. In other words, made it as simple as possible for your commenters to post, don’t make them jump through hoops just to leave some feedback on your site.
Disqus definitely meets this criteria by allowing your users to login three different ways to leave a comment on your site. I’m very impressed with the amount of growth I’ve seen in this commenting system and I will definitely be sticking with them for quite a while.
