Free Online Dating Services

Why would anyone pay for a dating service like Match.com or eHarmony when there are so many great free online dating services available?
I’ve joined a few Free Canadian Dating Services, now, and I’ll tell you, they’re just as good as the paid services. Match.com won’t be getting any more of my money, that’s for sure.
The paid sites seem to be making plenty of money still - I just don’t get it. What do they have to offer that’s so great? Nothing that I can see.
I’m sure I’ll have more to say about this down the line.
