Without an e-mail addr, how do you send notifications that someone has responded to a question or comment?
I saw the commentary about not keeping too much personal information. But without any e-mail addresses, how do you send notifications of activity? Without that feature, I don't imagine any future where I would use this site. It pretty much limits the utility to only those who are power users who will be checking it every single day. That's not how I use SE, and it definitely is not how I use SE at work... when I need a Stack Overflow question answered, I post it, and then I go back to work. I do not want to have to click back regularly to poll for results. So, question: What are the plans for sending notifications if you're not allowing us to submit e-mail addresses?
