I would say it's back from the dead:
- it's on coinchoose.com
- it has an exchange (
http://www.coins-e.com/exchange/PWC_BTC/ ) with lots of BIDS (people buying it)
- it has a working mine pool (
http://pwc.minepool.net/ ) with people mining it
It's still small but definitely alive.
Very easy to mine right now, difficulty is so low. People might want to take advantage of that before its price/difficulty rises.
