Congratulations SlinkSet team. Hard work pays off.
EDIT: I just spent more time at SlinkSet and I think they definitely have a business model in hosting their app as a HELP FORUM (excatly like the one they have on their site).
Writing a FAQ is very hard and you always leave some questions out. By hosting this feature for small businesses, they can also gather a lot of information about those businesses and their customers.
