Speed-dating events are most often held in restaurants and bars, although events are cropping up in other places, like student unions on college campuses.
One set of the speed daters, usually women, stay seated at the same table, and the opposite group moves from table to table.
This table-hopping method has been compared to musical chairs.
8 Minute Dating, a speed-dating service based in Boston, Mass., maintains the policy that none of their speed daters are allowed to ask for anyone else's last name or phone number.
Other services ask speed daters not to discuss what they do for a living or where they live.
When two people enter each person's name, they provide information so you can arrange a 2nd date.
