The Chula Vista Public Library in California takes a more "programmatic" approach to speed dating. It's book-oriented.
Link to February 5 Sign On San Diego post, "Literary speed dating on the books at library".
Excerpt: Adults 21 and older will have an opportunity to meet novel friends or a new love during the Literary Speed Dating evening. In a classic speed-dating style, participants will have five minutes with each partner to talk about their favorite books. The library, which is normally closed on Fridays, is open only for this special occasion.
