To clarify, this is a service similar to DropBox. It is currently free but it is clear they will introduce premium accounts soon (just like all the other cloud storage providers) and put a cap on free accounts (bye bye free infinite cloud storage ).
Bitcasa is currently free to use during an initial trial period.
It is a bit silly yes, here they are getting free advertisement and they make a blunder like this. From an announcement yesterday (http://blog.bitcasa.com/172191290) they promised something new for today, I guess we caught them in the middle of an upgrade gone haywire
