[Update: Cloud9 have promised to look at a clearer pricing model. See comments.]
Cloud9 IDE is a service with a good idea – provide an online IDE, and they seem to have several great features implemented. On the other hand, this is remarkably stupid:
It makes it seem that having a single workspace is 100 times less expensive than unlimited workspaces, when in reality it is only 1/3rd less expensive. When you see this kind of thing, you wonder what is going through the head of the person putting up this graphic. Do they think that people won’t notice, sign up and then not worry about the bill? Or do they think they continue to have a good impression about the service after they realize their mistake? Having put so much thought into duping customers, their home page fails to provide easy information on what programming languages they support in their IDE.
