There is something wrong with the whole WPMU/incsub situation. they are very heavy on marketing, and low on quality. I was a member for a while and used a few plugins, but when I got deeper into the plugin code it was a disaster: the code was not poetry to put it lightly. Incsub seems to be very strong on marketing and weak on ethics. We can learn from them on their marketing skills, which are great, and we can also learn from them on their lack of ethic, and aim for higher standards.
