Communication Features
Some dating sites such as Lavalife aim to give
their members as many opportunities to communicate as possible. In
contrast, compatibility matchmaking sites such as eHarmony only allow you
to contact members that they have determined are suitable for you.
These sites require you to use guided communication techniques to
connect with potential matches so that you can learn important
things about each other and let the relationship progress slowly
and naturally. As a result, compatibility matching sites tend to
offer fewer communication features than those that allow you to
search independently.
Icebreakers, Winks and Flirts
Although they are referred to by different names on different
dating sites, these terms all refer to your initial contact with
another single. When you see an interesting profile you can send a
virtual wink, flirt or icebreaker to announce that you're
interested in communicating without worrying about making an
awkward first impression.
Match.com
Match.com has a small smiley face
icon next to each profile you view. To wink at a person of
interest, all you need to do is click on the smiley face to the
right of the profile picture. Read full review Match.com
