Once a profile has been created, members can view the profiles of other members of the service, using the visible profile information to decide whether or not to initiate contact.A 2005 study of data collected by the Pew Internet & American Life Project found that individuals are more likely to use an online dating service if they use the Internet for a greater number of tasks, and less likely to use such a service if they are trusting of others.It is possible that the mode of online dating resonates with some participants' conceptual orientation towards the process of finding a romantic partner.Profiles created by real humans also have the potential to be problematic.For example, online dating sites may expose more female members in particular to stalking, fraud, and sexual violence by online predators.
Niche sites cater to people with special interests, such as sports fans, racing and automotive fans, medical or other professionals, people with political or religious preferences (e.g., Hindu, Jewish, Christian, Muslim, etc.), people with medical conditions (e.g., HIV , obese), or those living in rural farm communities.
