My phone number is a 10-digit number, the first 3 of which are an area code. It gets spam calls and texts (though that miraculously decreased on November 4th...) as it is. Now, combined with browser fingerprinting, perhaps this site can tie my specific 10-digit number to some other aspects of who I am, but I'll leave that part as an exercise for a willing volunteer. I'm not terribly concerned about entering my phone number, disconnected from other identifying information, into a random web site.

Convince me why I should be!
