Many people have a negative view of sites such as Eharmony.com or Match.com. They often feel that if they have 'stooped' to use the internet to find dates, that they are not able to meet people in person. Therefore, it is often used as a last resort by people, with the smell of desperation in the air.
However, registering on a dating website and using it as a tool to help you find some is nothing to be ashamed of. You should be ashamed if you are making up information or using someone else's picture on the site (don't laugh, people do this!) That is something entirely different, keeping in mind that everyone exaggerates a little bit. There is just a certain line to tow when making your profile, and if you are not sure if you are being truthful enough, you probably aren't.
That all being said, there are a lot of reasons why a person might choose to develop a profile on a dating site. Many people meet their husband or wife in college-just because of the sheer number of options that you have. When you leave college, you realize how much your pool of people to pick from is reduced as you live in a place (generally) with many more varied ages. Also, it is the easiest thing in the world to meet people while you are in college, and not always the case later on. It can be very challenging to find the time to go out and meet new people, let alone find a person that you are interested in starting up a relationship with.
Dating websites are just another medium of communication and a way to meet people. If you are a person who has decided to make the choice to be on one of them, embrace that choice and put yourself out there! If you are someone who has been considering joining but is unsure of how it will look, remember that it is just another way to mingle.
Stop thinking of this as somethign negative, embrace it, and get out there!
