I have met quite a few very pleasant people but we just mutually realized "not for me" after a date or two. We wished each other luck and parted ways. In the case of bumble in my experience there is an emotional maturity and interesting people. But apparently you are required to have a photo at Machu Picchu.
I agree, it does seem ridiculous: here in the DC area, it does seem that every single professional woman over 30 has such a photo.
But strangely, I actually have a photo just like that on my profile! It was taken at the NYC Natural History museum.
For women's profiles, the stereotypical photos are: 1) Macchu Picchu 2) at a bar with an alcoholic drink in-hand, frequently looking drunk 3) at a beach 4) in bed, cuddling with a big smelly dog 5) at a gun range These are pretty typical of 30+ white women in the DC area, though they're never seen all in the same profile (the women who like guns don't go to Macchu Picchu).
Also, you say that in your experience on Bumble, women are more emotionally mature. In my experience there, I'd say there seem to be more professional women there, but if you're not a big bar-goer and drinker, you're not going to do well there, at least in this city. Also, the women there seem to be almost all white and black; all the Asians seem to be on CMB, which is where I get the vast majority of my dates.
That's why you'd see so many great people and no match, they all left long ago. It's ghost town.
You probably get news matches when people sign up or come back, dating is very seasonal.
