If you're a busy professional like me, OLD is almost a necessary evil if you want to stay active in the dating market. I'm also over 45 so things like bar hopping, parties, etc. are out or limited. There are other avenues like the gym, networking events, and even the dog park so I try to see OLD as a supplement only. Still many of the women who are on OLD are unsatisfied with whom they've met IRL and are also busy with a career and maybe kids so it's just another way for them to try and meet people too. They're not all losers and BPD'ers as some profess here.
I haven't met many off of OLD who have impressed me and I've "clicked" with even fewer. I will admit my standards have gotten really high, especially the past year. I'm really not "looking" for a gf or LTR or anything like that, but the door is always open a crack if I do meet someone extraordinary. I just don't give up easily, I guess. Quitting is not in my DNA. I actually do OK getting dates on OLD, and sometimes I'll admit I just don't put in enough effort to keep things going once I do meet someone. It just seems like so much f*ucking work right now. I've been in successful relationships and am well aware what you need to do to keep things growing and moving. It takes a lot of time of which I just don't want to put in right now.
OLD isn't as bad as people make it out to be. It is a good tool for busy people, but use it as a supplement only, not the focal point. And have a life outside of dating. Dating and women should be a small side dish on your huge plate of food.
Good luck to you.
