As you probably know, Snap goes down from time to time. But at least it's got quite a few mirrors. Is there data on NetsBlox's uptime? i don't want to use this tool and then have it be unresponsive or down in class.
NetsBlox seems to have many new features from Snap! Does it run on top of Snap or is it a fork?
Is there a plan to introduce a text-based equivalent like PencilCode?
