I get their email announcements because I viewed one of their things years ago and have been to a number of photography events where one or more of the instructors they use has appeared, so end up on their mailing lists. I like to keep up with what is being offered out there and by whom from a number of organizations, as well, but personally have not found their paid offerings to be of enough value to pay for them.
They do have some interesting 'classes' for free if you are able to stream them when they are presented live.
One of the things that continually turns me off about them is their marketing and style of presentation of a lot of their classes. It's a little too slick for my tastes.
