My one complaint is that the Ziftrcoin team has been generally too quiet. Would be nice if they'd speak up to the community every now and then, even if just to let us know how things are going. 
I have this complaint too. Due to the Ziftr/GoCoin merger and some funding happening around it, we're all told basically to not say anything about it, or what's currently being worked on, until everything is in place.
I think I can say that, in my opinion, things are going great. There is always the chance of failure, but there are a lot of interesting things going on in the industry right now and we seem to be in a great place to be a part of it all. Of course, this forum being what it is, that statement essentially means nothing, since I have nothing I can back it up with.
