As the great philosopher, Confucius said: "Wherever you go, there you are." That depends a lot on who you are and what you're looking for....and most importantly, what you bring to the equation. The Castro is a fabulous place for singles in many ways- there are plenty of singles who live here, there's lot's of things to do (movies, dinner, local shows, etc), and it's a transit hub, so you can be anywhere you want in moments....and it's a great place for couples, families, gays, straights, and everything in between...
