From personal experience I'd say OLD has changed drastically (for the worse) over the past 5 years. When I was still in college, I probably went on 20+ dates from OkCupid. I was still in my blue bill days so I only got laid once, rest were LJBF rejections. However, the fact that I got regular dates suggests that women were way more willing to entertain the idea. OKC and POF are now garage, as far as selection goes (maybe POF was always garbage).
Now a days I'm on Tinder (I'm still in the same location / area) I'm lucky if I can get 1 girl to keep enough interest to go meet up. Generally what happens is the conversations just trail off, the ball was in her court last (conversationally speaking) and I eventually unmatch that **** because I'm tired of all these chicks sitting in my match queue saying last message was 7 (or more ) days ago. Or maybe I just need to work on some kind of Tinder/Bumble game. Hmm
