I absolutely agree, and I didn't mean to imply otherwise with my post.

There's nothing wrong with a passphrase as long as it can't be gotten in a reasonable timeframe, obviously! My point about generation stands, though - no password scheme stands in a vacuum, and if whatever you do catches on, you can guarantee software will be made to exploit the low entropy passwords on that scheme (for example, attacks can now include tricks like taking the website name - LinkedIn - and performing common mutations to generate passwords to attempt: L1nk3dIn1)
If it became really common, people would make rainbow tables for it too. All you'd need to do is create a reduction function that maps back into the set <passwords formed from concatenating common words> :)
This applies to all forms of password generation though: ultimately, entropy is important, and if you care about your security you should know whether the entropy levels of your passwords afford you the security you want or need.
