Open Letter to the President Follow-up

So, I sent the letter to "president@whitehouse.gov" and I got the following response:

Dear Friend,

Thank you for your message.  On behalf of President
Obama, we appreciate hearing from you.  The President
has promised the most transparent administration in
history, and we're committed to listening to and
responding to you.

In order to better handle the millions of electronic
messages we're receiving and respond more quickly,
we've implemented a new contact form on our website:
http://www.whitehouse.gov/contact/

Please note that this web form has replaced
comments@whitehouse.gov. That email address is
no longer monitored, so we encourage you to resubmit
your message through the link above.  Thank you for
using the web form and helping us improve
communications with you.

Sincerely,
The Presidential Correspondence Team

Hmm...I wonder why the president would no longer accept an anonymous email but now requires you to go to a website and enter your name, address, and zip code to send a message to "the most transparent administration in history." I bet anyone who uses statcounter or a similar service could probably answer that question.

Needless to say, I went to the website and submitted the comments. I have nothing to hide.
