I've had stalkers before and it'd freak me out if I received a thank you note from someone I did not exchange contact details with.

Interviewers typically email you to schedule the interview or share their business card with you during the interview...

I've interviewed ~5 times in the last year...did not receive any business cards or email addresses. The recruiter/HR person actually denied my request for their email address when I asked for it in order to send a note on more than one occasion.
