Not all. Some cryptocurrencies are Proof of Stake instead of Proof of Work. This means that in order to try and do a 51% attack, the attacker must have 51% of the staking coins. PoS uses magnitudes less electricity than PoW and game theory suggests it's just as, if not more, secure.
Yep, this is an interesting pattern in a libertarian (essentially, they are ignoring laws for now) society. They will provide good service and rates until they have a monopoly and can maintain it. Then, they'll abuse the customer until a viable alternative pops up.
How is this "antisemitic"? Jewish people are disproportionately represented on NPR's staff. I don't see this as a problem, but talk about a speck in your brother's eye when you've removed the plank in yours. Live by the sword, die by the sword.

I used Cloud9 for a while. The lag from typing on my keyboard to showing up on my screen became pronounced that I stopped using the service. I was on the free tier. I can see the appeal, but the execution of this service was too poor for me to use. Perhaps in the future I'll try again.
Nope, go on 8chan and other controversial sites. You don't have to like what they say, but you'll get interesting ideas and points of view that people won't say on mainstream sites like HN and Twitter. Seek out writers and sites you don't agree with and read stuff that makes you uncomfortable.
