I still need to complete my series on online dating, but first I wanted to further discuss the topic addressed by Francine on Geographical Impairment. I think it is something to which most LDS singles can relate. I have asked my self those same questions for years and at times have felt that I needed to stay in the "Mormon Centers" of the world or I would never find anyone. Other times I have believed that upping the quantity doesn't necessarily up the quality, and that you can find love anywhere.
Many years ago when I was studying at BYU and living in Provo, Utah (Mormon center of the world for those of you unfamiliar with our church), I remember nearing my graduation and feeling very panicked about the future. Was I worried about trying to find a job with my generic B.A.? No, I was worried about leaving Provo and never finding anyone to marry. I couldn't leave Provo as a single! So I stayed, dated a guy, and a year later I still left Provo in a state of singleness.
As I already mentioned I have gone back and forth on deciding where I need to live, and what are the most important factors. I have lived on 4 continents, in 5 countries, and in 7 cities. Some have been Mormon centers, and others have been cities with very small LDS communities. Each place has provided diversity, new experiences, and a new dating pool, however one thing has always been the same: I remain single.
What I have concluded from my history of moving around, and feeling the pressure to live somewhere with a lot of singles, is that you can meet someone anywhere. For every story of two people meeting and falling in love at BYU, there is a story of someone going to a ward in the middle of nowhere thinking he/she will be the only single, only to be introduced to another single and then finding true love.
Therefore, I think it's about identifying your needs for happiness and contentment, and finding a place that satisfies those needs. For the past 2 years I was living outside of North America in an area with less of a Mormon culture, and less members. The dating pool was smaller, but people networked and we still managed to date. When I came to the age of YSA expiration, I decided that I wanted to be near my family, and that I also wanted to live in a city with other LDS people in my age bracket. I knew that I needed a network of people in my situation so that I could survive attending a family ward without a family. Living here has proven to be what I need at this point in my life and although I have struggled with finding a good job and good friends, I am happy being with my family and I have had more dating opportunities than I did even back in the Provo days.
Francine, not sure if any of that was useful, but those are my thoughts.
