Connecting with Members

I just got a PM from a user who said "Hello! I'm <username>. Nice to meet you! Let's connect." What I know about this user is precisely zero. Before I respond to a "let's connect" request I'd like to know a little bit about this user. In the old Daniweb I would just go o that user's profile page and read whatever he/she had decided to share. How do I do that now? And if I can't do that, what incentive do I have to respond?
