My $0.02: Read the comments, particularly the negative ones, and try to reply to every single one. 99.999 percent of the time, people will flip the switch from negative to positive when confronted directly. They realize "hey - this is a real person behind this company, and they are taking the time to address my concerns personally." Often, their negative perspective can be reversed with better communication and clarity about your product / goals. Also, the people criticizing your product may very well be right. There were plenty of times when I did not place enough weight on some criticisms, and they were in fact right. Take criticisms seriously, it is too easy to get tunnel vision and convince yourself you are making all the right choices.
