I was disappointed... which sucks. Back before release I did have a lot of concerns - not least that the money and hype would not leave the right environment to work in.
Once the product was released I had a number of concerns:
* The security is abysmal, it needs a complete audit and someone with real experience here (plus maybe months of work) till it is safe to use
* They didn't seem to have done very much. The UI appeared to have a lot put into it.. but only on the surface, at any depth it became confusing.
I'm afraid that I think they shot themselves in the foot dramatically here. Because they rose to the hype with a pretty poor "product" - so now many supporters are disillusioned with their promise.
It will take a lot of time to create a working system; months at least. This was always going to be the case, but the hype forced them to promise something much sooner. And now it is a "semi-failure".
With luck they can refocus and come back in a few months with a serious product :)
