HN Review my 4 hour hack project: Secret Mentions

I hacked something last night, the idea is simple: Allow people to send secret messages to people on twitter.

URL: http://secret-mention.appspot.com/

How it works:

-> Tell us the recipient of the message, write your message

-> We create a webpage containing your message

-> And send the recipient a mention with the link

-> We don't know who you are, so your identity will be secret

Please let me know what you think, feedback, ideas and of course if you think there could be a pitfall or risk let me know.

Thanks HN!
