The slow approach tends to produce better outcomes than the volume one — it took me longer than it should have to work that out. Would like to hear what actually happened — especially anything that went badly. What are the free video dating websites where people actually show their faces?
For what it is worth, vague profiles get vague responses, or none — it took me longer than it should have to work that out.
My take: patience is genuinely the differentiator, dull as that sounds — your mileage may well differ.
