You bringing up things being different in New York City made me remember that if you compare the proportion of women and men of New York City and Los Angeles, you will notice that there are more women than men in New York and the opposite in Los Angeles. Now this fact alone may not be enough to conclude that based on these ratios that it is the cause of such a change in quality of women. But from another perspective it makes sense. In Los Angeles and in California, there are less women. This means that women have a much larger pool of men that they can choose, so they can afford to be picky. This means that the proportion of good looking, successful men using online dating increases since there aren't enough women in the local area to date. Now New York on the other hand, the advantage is for men as there are more women and they can be picky. This means that even attractive and interesting women now have to make themselves publicly available via online dating.

Of course this is just a hypothesis so of course this may not be the case.
