Disqus is great. I switched blogging software so that I could have out of the box Disqus integration. I hope they take their competitive advantage (they're just a little bit better than the alternatives) and sustain it. FriendFeed and others are catching up, but I suspect with their heavy hitting VCs guiding them, they'll stay ahead of the pack. I particularly like their open attitude about downtime and service quality. When they screw up, they post about it on their blog, apologize, and explain how they're getting better. This appears to be one item in the recipe for success.
