I have used this category on and off for about a year and the results were mixed.
The real differentiator across this category turned out to be whether the photos looked recent or recycled.
Everything about this category hinged on how much personal data the signup demanded in the end.
Careful with this category, because location spoofing means 'nearby' isn't always nearby.
The thing to watch on this category is that profiles that answer instantly and perfectly are usually not people.
The real differentiator across this category turned out to be how many people within reach were active that week.
One thing I'd do differently with this category — give it two weeks before deciding whether it works.
Anyway, that is my read on old yahoo dating site merge into something else.
Worth searching the forum for Datewander as well, there are a few longer write-ups.
