I can't imagine someone with your amount of history would be so ill informed? Darkcoin is quite anonymous. Have you even read how it works? It's my own implementation of coinjoin that is much more anonymous than anything offered on the bitcoin network, plus it's not vulnerable to any of the coinjoin attacks (coinjoin sudoku). It's decentralized, secure, timing-attack resistant and it works on mainnet, right now.

I'm going to just guess that you haven't actually done any reading about Darksend and show you how it works:

Here's an example transaction:

So the gist is if you put 550DRK into the pool, it'll be broken down into 100DRK*5, 10DRK*5 and paired with the same denominations from another user. So after that transaction, no one can tell who is paying for what.

It's also very low bloat compared to monero /bytecoin because it only happens when it's needed. The whole blockchain is 346MB right now. Monero is not even close to as old and already is many times that size.
