Ha, I can guarantee you it's not even close to being a trap. Look at my blog, twitter feed anything, most certainly isn't a trap. The login box is for finding your people in your contact list that have been compromised and uses OpenInviter to return the list. If you want to see if you have been compromised then simply do a search in the search box below the login box, no need to enter details if you don't want to.
The main reason I added the contacts list functionality is I noticed Lulzsec recently posted a database dump of 25,000 users they preened from pron.com. I thought it would be humorous to know which of your contact had been busted looking at porn... ;)
