Not really anonymous, not BTC.. for example if you take the address in my SIG (which has 0 use so not such a good example but eh)

[link to blockchain.info (secure)]

Same can be done with any address to examine what is happening with it, and where funds are coming/going, etc

There are coins out there being designed around Privacy, but BTC isn't one of them heh

The anonymous in the title of the article (which I just cut and paste into the thread title) probably refers to the fact that many of the "big players" are known, using known addresses, etc
