Online dating websites are a great way to meet people you would not in a different way. In the pre-internet days, your best chance of meeting an eligible single person was an introduction agency or a matchmaking friend. Otherwise your chances were limited.
The internet has made a huge difference to the romantic prospects of a whole generation of people. Instead of waiting for Mr or Miss Right to show up in the local pub, you can now browse through thousands of dating profiles from people living hundreds of miles away. If you see anyone you like, you can contact them and strike up a conversation online, which for a shy person is a real ice breaker.
