Kindle KDP Select - Is this a good or bad idea?

I have just recieved an eMail from Kindle KDP and am undecided on whether to join.

Hello from KDP!

We're excited to introduce KDP Select - a new option dedicated to KDP authors and publishers worldwide, featuring a fund of $500,000 in December 2011 and at least $6 million in total for 2012! KDP Select gives you a new way to earn royalties, reach a broader audience, and use a new set of promotional tools.

Here's how KDP Select works:

When you make any of your titles exclusive to the Kindle Store for at least 90 days, those with US rights will automatically be included in the Kindle Owners' Lending Library and can earn a share of a monthly fund. The monthly fund for December 2011 is $500,000 and will total at least $6 million in 2012. If you haven't checked it out already, the Kindle Owners' Lending Library is a collection of books that eligible US Amazon Prime members can borrow for free once a month with no due dates.

If you have received a similar eMail, what are your thoughts?
