I've been mocking up a Wordpress blog for the company I work for. Anyone who has spent time with Wordpress knows that the commenting system is prone to abuse without paying for a service to vet the comments.
Disqus is a service that does this for Wordpress as well as a number of other services. What is better is that they allow you to use your social logins as credentials to keep from having to create an account for every site you decide to leave a comment with.
After I installed the Disqus, I noticed that the width of the comment block was not being inherited from that above it and some of the text was being cut off.
A big thank you to Alex Dresko for posting his fix so I don't have to spend an afternoon hunting through 5700 lines of CSS.
