If you simply delete your account, the comments live on but are anonymized. The username is [deleted]. It's a lot easier than deleting all your comments before deleting the account, and as others have said, it preserves the conversation for future people. I'd much rather learn what a bunch of deleted accounts thought about in a thread from 10 years ago than getting only a partial conversation.
