Become.com Out of Beta

Yesterday I received an email from Michael Yang, in bulk, saying, "We are opening our site to the general public." Become.com is a search engine vertical focusing on the shopping niche. They have received some good PR in the past, so a lot is expected of them.

Here is the full email, for some reason, the email had a blank subject. To me that seems unprofessional.

Dear Become.com Beta Testers,
On behalf of everyone at Become, I would like to thank you for using Become.com. Your feedback has been invaluable to us as we continue to improve our service.
