Personally, I use online because it's a great tool for filtering certain personality traits and behaviours in people. I don't care much about looks. (other than having a human bmi, of course) What I most require in a potential mate is that they are vegan because I am vegan and I want someone that shares my same lifestyle and is compassionate like me. But with 79% of vegans being female it's very difficult for straight female vegans. Then you also have to filter out lgbt and those who don't want to marry. This leaves me in fear that I won't find a husband.
