Had a great meeting last at Caffe Umbria with Michael Dougherty, the CEO and Co-Founder of Quorus. They are doing some very cool stuff helping sites connect with their users including a couple of tools that allow real time chat between users viewing the same page (very helpful in allowing users to discuss products in real time) and simplified member sign ups. It is a great way to add value to your site. Get in touch with them to help drive engagement and conversion especially if you are in the e-commerce space.
