Congratulations. You're the fourth (fifth, if we count hypothetical Nakamoto) person (maybe more, if we assume the moderators currently modding me back down also share the same misconception) who seems to have no understanding of how the Internet works and what the effect is has on privacy.
You are correct that logging, by itself, makes no difference. But logging is one of the key components of Bitcoin that destroys the ability to be genuinely anonymous on it. For more details, I suggest you read the response I made to the second of your sibling posts. But essentially, to re-iterate, the more you use a wallet, the more information "leaks" about you because the logging exists, is public, and will, from time to time, involve you making transactions with people who know you. Without the use of an extremely trustworthy Bitcoin laundering service, it will be the case that ultimately any well connected retailer or employer can find out what you've been spending your money on.
Comparing it to posting AC on Slashdot is inane and absurd. Indeed, even posting under a pseudonym on Slashdot, as I do, grants me more privacy than my attempting to use Bitcoin to buy both Samizdat and food.
