[So what happens when you switch jobs, or a virus deletes your C drive and you have no bookmarks?] = I backup regularly. Backup. Backup. Backup.

[How do you visit the site then if you don't easily know the address?] = I Don't.

[Or what about when you're at a party chatting with someone and you say, “Hey, I just read about that at this great blog. What was the name? I know it, I just have it bookmarked. Oh well.”] = I don't go to parties. 🙂
