I'd be scared to date online. I'd need a personal reference. Someone to vouch for the person, not some bogus questionnaire. Just my opinion.
It's not like you just go through reading questionnaires, pick the one you like, then meet that person. I only ever met my wife, but I talked to several through e-mails, texts, and phone calls. I was not going to meet someone till I felt comfortable that we could possibly have a connection.
