@london203 no offense taking. I work for UX group at a major software company. It pains me to toggle between Parents and Cafe for no real benefit. I really only read the latest posting in each. And I suspect that is what most people do.
I think the logic that someone has to work with something for a long time to know if it works or not is false. Take the iPod for example. People knew immediately it was great. Now take Windows 8. It was a dud right out of the box.
