In case you’ve missed it, we’re now in the opt-out period for this mechanism. Feel free to opt out–and sacrifice all your data.
Here’s thow to do it (from the FeedBurner login page)
NOTE: Service of FeedBurner publisher accounts will not be interrupted as a result of the acquisition by Google. You will have a 14-day interim period ending June 15, 2007 to opt-out of allowing Google to service your account. If you take no action by June 15, 2007, the rights to your data will transfer from FeedBurner to Google. Opting out will terminate your user agreement with FeedBurner, permanently delete your FeedBurner account, feeds, and all related statistical data and history, and prevent the transfer of your data rights to Google. To opt-out, contact us via email@example.com, provide your FeedBurner account Username, and request to have your FeedBurner account deleted. We will contact you at your registered email address to confirm your deletion request before completing it.
I’m not much of a conspiracy theorist. I’m not overly concerned about Google collecting my data. But losing all your data if you disagree? At least you can export your data before your account is closed forever. If you’re leaving FeedBurner, be sure to notify your subscribers before you delete your account.
