Take your strengths and leverage them, then leverage further.
Example...
Mumsnet - time management is a regular topic from 1000 perspectives, with one thing in common. How to manage their time more effectively so they actually have time for things like - dating.
If your site was a 'Time for Dating' site and you mashed up the time management software angle into the dating for single parents angle, suddenly you've got 2 reasons for them to keep paying that monthly renewal fee, instead of the one trick pony like most others.
Example...
Social media profiles and history say a lot about someone. Grab an API for social history, grab an API for sentiment/lexical analysis and a couple of hours later you've got NOT what the person says about themselves being all conservative, shy, homebody who is a vegan aerobics instructor and find that they spend more time talking about burgers and beer, in between colourful expletives than 99% of the military grunts.
Example...
You could mash up locations with dating rating and create your own composites of where and where not to go on a first date, based on actual success and failure. Places too noisy, too this or too that... Coming up with ideas for where and what is always a source of anxiety, so add a new spin to it by making it easier to decide.
Connecting men and women, or men and men or women and women is a great idea. It's a rough river to try and cross without help. Narrow that sucker down to the point it's a babbling brook or a wispy tidepool and suddenly you've made it to the other side.
UNIQUE Selling Point - if 100 competitors have it as their USP, then it isn't exactly unique!
So put your thinking cap on, think like a single parent, figure out what their challenges are in dating and help them overcome it while facilitating them connecting. Maybe their social channels are aligned by both being big fans of some obscure dog breed, or they both Foursquare on Tuesdays at V&A Museum. Sure they haven't connected the dots, yet, but you can - if your coding is up to the task
