Honest feedback:

I visited Tusulog (the name should be re-evaluated) and there was very little description of what it is, what it does, why its good, etc.

I then registered and was told that the service was meaningless unless I invited friends. Ok. Try to wedge out of the chicken and the egg, or piggyback on something else, because in all honesty, theres no way I'm inviting friends to a service of questionable value.

Something something "its not what your service does, its how people use it". Right now, for all I know, Tusulog is the most genius website ever made, I just wouldn't get to the part where I discover that.
