Just a reminder that the multiple accounts under HitTail are not as bad as it sounds. You simply register multiple times, using a very short registration form, and use the same email account every time. Everything gets tied together on the email account, and when you log in using your email account as the username, you have access to all your accounts.
Hittail will not only log your long tail stats, but also recomend new keywords for content ideas that will get you more clicks. I've tried it and it works pretty well.
