Seems like an interesting coin. I noticed all the altcoins are steadily increasing in popularity; since BTC is getting more expensive to get, I'd expect the altcoins to really make leaps and bounds from this point out.
Yup. Especially the coins like PPCoin which actually offer a distinct advantage such as energy saving.
Sunny the developer is also extremely active unlike the devs of most other alt currencies. He even fixed a vulnerability in TRC the other week.
