Right now I'm working on further optimizing CPU mining. GPU miner is inevitable and we want CPU mining to be more competitive to it when it will appear and if this miner will be private we want network to have higher hashrate compared to any GPUs which will use it. If all goes well I will release optimized version today.
After that I will hold a giveaway (or several giveaways in different places) to spread SpreadCoin.
Mr. Spread, if there are some interesting and still unimplemented concepts in bitcoin that you still want to implement?
Yes, I already wrote about it:
I have several great ideas about possible features (never implemented before in other altcoins) in addition to poolless mining but they all require thorough design and thought so they will take considerable amount of time.
You, of course, want to know what are these ideas but I cannot disclose them; other developer (or even a team) can steal my ideas and implement in other coins. What I can say now is that I will not introduce any new controversial changes (e.g. pool absence is both good and bad as you said). All further changes will be strictly positive and will not be disruptive (i.e. changing mining algorithm is probably not an option).
Anyway, any new features can only be introduced in a more remote future, currently we need to focus on promotion and exchanges.
