It's been a couple years since I'd been in the dating pool, fortunately. One thing that consistently annoyed me back then, was the number of people on dating sites that "didn't have time" to actually meet/date. At the very least it's probably somewhat easier to figure out who is serious about dating and who isn't.

One has to actually take the time to make things happen. Most people have much more free time than they realize and it's a matter of priorities.
