Thanks for the great feedback. It is an abstract variation of a communication being driven through the air at speed. I wanted to somehow represent what you do in a way that instantly gave off simplicity and speed. Please let me know if you would like to see any changes made, no matter how small.
Some of my partners really like the abstract logo on #4... Can we do something with the text to make the text pop a little more? Maybe some web 2.0 stuff like in your portfolio? Thanks!
