darkcoin is far from a finished product and development continues. most of the issues fluffy brings up are known and in fact already have a solution waiting to be implemented. the new masternode blinding thing evan is working on along with ip obfuscation takes care of most of the issues he drones on about.
masternodes are located all over the world and out of the nsa or any single-entities jurisdiction so the whole warrant snooping thing is ridiculous. don't you need like 90% of the mn to see 1% of the transactions, something like that.
the cryptobloat vs darkcoin debate is over and darkcoin won. darkcoin won before xmr even had a working wallet, if you thought their bloating was bad before just wait till people start to use it as intended. they have a huge inflation problem and are not future proofed with their inferior on chain mixing as pointed out by AnonyMint. their incompatibility issues have already seen them snubbed over drk when it comes to adoption and their cryptography is unproven and sure to have more (serious) bugs found in the future according to peter todd.
fluffypony can ramble on until he is blue in the face but the market has spoken and the debate is all but settled, instantX will be the final nail in the coffin.
