Ok, so since the release of Sitefinity 4, we've been saddled with a pretty basic commenting system...for example still we have no hierarchical threads, email notification system, and no ability to add a thread to a generic page.  At the very least I'd like to get an email when I get a comment so I don't have to check back daily for feedback right?

So, say goodbye to Sitefinity Comments, and hello to DISQUS on sitefinitysteve!

Very easy to implement, if there's demand I'll make the widgets available in the marketplace.
