How does this improve, or differ from, Toktumi (http://toktumi.com/Whytoktumi.aspx)? At first glance, they appear quite similar, with perhaps Toktumi edging ahead on features.
One of our main focus points is usability, building something that anyone can sign up and use immediately. we actually removed a number of features pre-launch, just so it make the core functions as simple as possible.
