Is there anything better than the Disqus Ruby Gem? Perhaps something geared specifically towards Rails?
(The Disqus gem might be the best option, I just haven't been able to find much color one way or the other).
The Ruby gem's helper just embeds Disqus' native Javascript, which is bad because it loads the Disqus comments synchronously.
Rather than make users wait, I did some hacking and got the comments to load asynchronously. Check out my blog post on the subject.
