It's not just that, modern dating fucking sucks. People don't naturally run into each other nearly as much, and most people aren't in a mood to 'meet people' when they're not looking. Going online also just reduces everyone down to an online shopping wishlist where men are so desperate it gives women an infinite selection of dick (which IMO doesn't really benefit anyone, because women have to do all the decision making in that environment and it can be overwhelming, especially if anyone is looking for more than that.)
