I just saw this question and I have not read 3 pages or any of the replies. So please forgive.
I think I am the only person that I know by my age who has never been on a dating site. In my most strong and humble opinion, I think any online dating site is thee worst way to meet people. I know of one, ONE successful coupel who met on Match.com 14 years ago? They are happily married, have one child, a great life. But keep in mind, that is one in a million chance. I'm sorry to say this, but most men on there are married, or single and not looking for anything but a hook up (but would never tell you that) or perverts.....sometimes all 3. The women on there are very emotionally damaged. Don't get me wrong, there are some normal people who go onto these sites with innocent intentions but for whatever reason, these dating sites can't help suck you into the icky world and then very quickly contaminate you. My roommate who is 36 years old, is a male. He always goes on these dating sites, get's all the sex he can from one woman while promsing her the world, get's the lady to fall in love with him, then dumps her leaving a very broken heart. I get on his honeysuckle constantly for that and I made a rule that he is not allowed to bring any guests here and that has helped curb him from doing this shitty behavior. I'm saving some stupid females from very a broken heart. It's my little contribution to the world. I'm writing all of this as he is sitting next time eating a bowl of cereal and watching a cartoon.
And it doesn't matter how old you are, the majority of people on online dating sites in my area are from 30 years old to 70 years old and they are the WORST. They act worse than young adults. Do not be fooled by age. You literally have no idea. I have endless messed up stories from these people.
