Well, it worked for me :) following an acrimonious separation from my spouse.
Within hours of signing up I was chatting to several very nice ladies.
I met one for a date after 4 days of chatting; 5 days of being on the site.
We then met every other day for a week and we're now inseparable after 3 months together.
Maybe I got lucky but I think if you're honest, open, pleasant and realistic you stand a very high chance of several dates or even finding a long term partner.
Just to update my original review... I've not revisited POF since my last comment.
After 18 months together we are still inseparable and very happy:)
Wedding bells? Well time will tell and I'll add a further update when it happens!
