Fitzmertz: 1) Some people will be always unhappy (I don't mean MadMonkey but I could name a few).
2) No product can make you 100% happy forever. When I bought my current home computer in 2006, I had been very happy and satisfied with it. Now I am not but it does not mean that I would start to send unhappy emails to the vendor and ask him to make the disks faster and WiFi adaptor more stable.
3) The Paid Membership page clearly describes what you get when you buy a membership. It says nothing like "once you become a paying member, the site owner is committed to make you happy until your membership expires".
4) It is very important to keep a balance between happy and unhappy people on BrainKing. The past showed us that all attempts to make everyone satisfied are direct ways to our doom.
