My understanding is that Dreamcoin said they had fully implemented zerocoin; this was not the case. All dreamcoin is was a clone of another coin. Sure they might be implementing it but it's never a good sign when they say its ALREADY implemented and wasn't.

Regarding complaints about updates/lack of progression; I sure as heck don't know how to code and I could throw lots of money at something but it doesn't change the fact that this project isn't the dev's dayjob. Give them some space let them do what they do; they are continuing to make changes and commits. Regardless of when this comes out; I'll be happy because it offers a strong alternative that isn't some quick pump and dump scheme to enrich a select few. On the otherhand if you start to see massive changes in the network and coin supply; hold on to your coins because we will be in for a bumpy ride. TLDR: Keep calm and anon on.
