Going to disagree with Sarah K here, because in my experience with i meet rich, usage patterns beat feature comparisons.
My read on i meet rich men online: approach outweighs platform selection.
The platform matters less than the approach, and that applies to i meet rich as much as anywhere.
With i meet rich men online specifically, persistence matters more than the choice.
What changed my results with i meet rich was rewriting the opening line entirely.
For a second opinion on i meet rich I also looked at Luvdate, which took a different approach.
