For alot of people, internet dating is usually the very last resort. They've tried everything, and nothing seems to work.
If you've exhausted all of your options, then internet dating isn't necessarily a bad thing. Actually, internet dating isn't a bad thing at all. It's just that alot of people find weirdos on the internet. It doesn't work as well as meeting someone in person. Anybody can be anybody they want on the internet, and usually when you meet them in person they are not what you expect at all.
If you decide to add a profile to a dating site use something legit, like eharmony, or something similar. Good luck.
