I checked it out. Used CC from there.
And when C2 began to be discussed, it caught my attention, I saw the potential.
The very first public release did not hook me that much (it wasn't particulary featured truth be told ^^).
But quickly after, as it was getting more and more featured at an incredible pace (a matter of months with releases each couple of days at some points) I totaly went to use it in priority and became more involved in the community.
In my eyes C2 is superior to CC. It's subjective and mostly a matter of taste, but just consider the way you use variables in expressions in C2 compared to CC. No more tedious global or value arrays. Haaaaaaaa
I still have a lot of appreciation and respect for CC though, as I learned such a great deal from it and it really paved the way for the fantastic tool that C2 is now.
I'm also expecting the soon to be released next version of CC.
I think its users will be thrilled and it will shut some of the rumors of CC being abandonned.
