It is possible that the mode of online dating resonates with some participants' conceptual orientation towards the process of ﬁnding a romantic partner.
That is, online dating sites use the conceptual framework of a "marketplace metaphor" to help people find potential matches, with layouts and functionalities that make it easy to quickly browse and select profiles in a manner similar to how one might browse an online store.
In 2008, a variation of the online dating model emerged in the form of introduction sites, where members have to search and contact other members, who introduce them to other members whom they deem compatible.
Introduction sites differ from the traditional online dating model, and attracted a large number of users and significant investor interest.
Because online dating takes place in virtual space, it is possible for profile information to be misrepresented or falsified.
While some sites conduct background checks on members, many do not, resulting in some uncertainty around members' identities.
Members can constrain their interactions to the online space, or they can arrange a date to meet in person.
Such companies offer a wide variety of unmoderated matchmaking services, most of which are profile-based.Opinions and usage of online dating services also differ widely.
