We stumped quite a few Seattle-area techies with our trivia questions Wednesday night at the TechFlash Holiday Party & Birthday Bash. A few doozies -- including questions about FreeInternet.com, Urbanspoon and Amazon.com's original name -- really left attendees scratching their heads.

We published the questions yesterday on TechFlash from the big event. Now, here are the answers, below. Also see this PDF for the answers to the handout puzzle sheet. How did you do?

A good individual player would score more than 15 correct answers and a great player would score in the twenties. If you got more than 30 correct -- as TechFlash trivia champion Cheezburger Network did -- you'd better come out next time and show off your knowledge. Here are the questions and answers:
