Some people really enjoy online dating, and many very successful couples have met through an online dating service. And while dating via the Internet does present its problems, so do all types of dating. Even in the real world, people lie, cheat, and hurt others. Fortunately, most people are just looking for someone to be with.
If you currently date online or if you are considering trying out an online dating service, just remember that the people you chat to are real, even if they are not exactly what you imagine. Behave as you want others to behave. Do not be flaky, and do not lie about yourself; this will not help you meet anyone. At the same time, do not be overly trusting. People need to earn your trust, and this cannot be done online. Make an effort, keep realistic expectations, and have fun.
