1. Congratulations!

2. I don't get how it works from staring at the homepage I don't get it after the tour, the thing I am missing is...how does it benefit me

from what I understand after studying it (normal users don't do this) the product pulls in facebook,twitter and feeds into one feed and displays social popularity as well?

3. you probably want a copywriter to check it up as you have cut-off sentences and things that don't make any sense like "facebook, twitter and linkedin are in your help"

4. use usertesting.com or something similar
