Contact information cannot be traded during the initial meeting, in order to reduce pressure to accept or reject a suitor to his or her face.
There are many speed dating events now in the United Kingdom, Canada, and the United States.
Furthermore, issues such as religion, previous marriages, and smoking habits were found to play much less of a role than expected.
Many speed dating events are targeted at particular communities: for example, LGBT people, polyamorists, Some feel that speed dating has some obvious advantages over most other venues for meeting people, such as bars, discotheques, etc.
in that everybody is purportedly there to meet someone, they are grouped into compatible age ranges, it is time-efficient, and the structured interaction eliminates the need to introduce oneself.
Because the matching itself happens after the event, people do not feel pressured to select or reject each other in person.
On the other hand, feedback and gratification are delayed as participants must wait a day or two for their results to come in.
Most speed dating events match people at random, and participants will meet different "types" that they might not normally talk to in a club.
On the other hand, the random matching precludes the various cues, such as eye contact, that people use in bars to preselect each other before chatting them up.
In the UK, there are two companies that run events in more than twenty cities: Speed Dater and Slow Dating.
The largest speed dating company in Australia is Fastlife. Several online dating services offer online speed dating where users meet online for video, audio or text chats.
Hurrydate was acquired by Spark Networks (Jdate/Christian Mingle). The advantage of online speed dating is that users can go on dates from home as it can be done from any internet enabled computer.
