My friends and I have tried it in the past, Male and Female. In our experience it was expensive, time consuming, and when you finally met the person they were no where near their profiles.
We found Meetups, Habitat for Humanity, and other activities were a whole lot better in meeting a person in a real environment. We are all active outgoing and professional so let that temper our combined experinces.
We do have three (3) friends who have met their Husbands thru online dating. Two were off of Match.com, one off of EHarmony. Not a high success ratio, when you consider the 50+ folks I know who have done and left the Online World (6%).
Do note Tinder is a Hookup site for 20 Somethings. It is a "do you want to **** Ap" same with Kettle of Fish.
There are predators out there (M&F). Most profiles are Bogus. Most Pictures do not show you the real person. On one the persons profile pic was 20 years old. The list of profile deficiencies is long, positives is short.
The promise of online dating "one can find perfection between the Couch and the Refrigerator" is appealing. The reality is far less.
I do know three woman, 2 single 1 married, who troll Match.com looking for Hookups. I think for men it is similar numbers
