what exactly do you have in mind that requires active developement?
agreed on the gpu miner, but oh well... would be a shame if we got 51%'d like FTC
An active wiki like the one's up for bitcoin and litecoin in their github account's. And binary release's on the main github account would be a nice start. Yacoin is orphan since the original dev is missing, but this should not be a problem since a distributed coin is owned by their holders and with consensus anything could be changed. Essentially I am talking about an *official* yacoin takeover.
But.. wouldn't that defeat the purpose of YAC, aka being mined only with CPUs?
Since there is people already mining YAC with GPU. This only makes the currency unfair and insecure. So a public GPU implementation could only improve the security.
