I am a proud and happy user of the Postmatic/Epoch combo. It really is what the future of WordPress commenting should be - and yes, it should be deployed on WPTavern.

In fact, I'm sure if Jason is selling, but I'm also of the opinion that Matt & Co. should consider and acquisition to put Automattic's resources behind and to embed this power of into WordPress.com. This should be the standard commenting functionality of WordPress as a whole.
