Best JavaScript commenting library

At Viima, we're building a SaaS product where people should be able to comment things. We thought that since it's such a common need, there must be a good open source javascript library out there to do the job so that we wouldn't have to reinvent the wheel.

We scoured the web but couldn't really find anything that would work for us so we decided to build it by ourselves and have now released the library as open source: http://viima.github.io/jquery-comments/

What do you think? Is this the best js commenting library out there or is there something even better available?
