I think AKA_Monet has the right of this one.
A good movie to think about is "50 First Dates" with Adam Sandler and Drew Barrymore. The lesson is that on any given day you might succeed or strike out with someone.
You might meet a person on Tuesday and hit it off but if you had met that person on Monday you would have struck out. The timing could be off. One of you could feel bad. Or you just might be out of synch.
Dating someone you don't already have a lot of interest in is a way to see if you hit it off over a few dates. This is assuming you find them basically attractive. Or at least nice to look at.
I also think that AKA_monet is right on with her "Continuable Dateable Education" idea.
