Difference between ETH and ETC

[f00ch0w]

So I was reading a bit about the difference between these two cryptocurrencies. It would be nice if someone could explain it briefly to me, a newbie, what's the point of it and will it stay as PoW when ETH switches to PoS?

Will it be profitable to switch to mining ETC once ETH goes PoS? Thanks!

After the fallout of the DAO fork, ETC was opposed to the fork, so it continued on the original blockchain. The two chains are independent of each other as of the fork, so ETC will remain unchanged if ETH moves to POS.
