It would be interesting to follow this. However, I could see where this would get fairly personal if you were to meet someone you really liked (however, at that point, I'd guess it might be less of an online relationship than it would be a IRL relationship.)
Personally, I don't have much experience in online dating. A friend tried to hook me up with someone through a chat. That seemed to go very well until she asked for pictures of me:
silence
"How tall are you?"
Really tho. That's your first question. Can't even compliment my sweater (It was a nice sweater.) Really tho?
Granted, I'm short for most American women, let alone men, and I do recognize that most heterosexual women prefer their romantic partners to be taller than them. But I wasn't in the mood to "overcome" something that I really don't feel like I should have to overcome, so I really didn't try much after that.
Anyway, the experience up to that point was pleasant (and we just sorta stopped talking after a while, so it's not like it ended on a bad note with me calling her shallow or something, because I really don't think she is.) I might consider dating services once I'm out of school for a bit.
Just like people find friends online (because you frequent communities where you already know you share an interest/set of beliefs, and a lot of other factors (e.g. looks, IRL interpersonal skills) don't get in the way,) you probably might find some people you're interested in dating online as well.
I do wonder how often these relationships end once the people meet in reality for the first time/first few times. I'm very cynical about relationships, and I think looks play a huge part in determining whether or not you continue to be attracted to a person.
I remember a time where a person I know developed a crush on a person of whom I spoke highly. The first person sorta developed a crush on that other person, but when they actually met, the first person was very honest with me and lost interest primarily based upon the second person's looks.
I know it happens. I'd like to see how often.
There is a stereotype that people who date online are at least somewhat desperate or at least reclusive and don't meet up with friends much. Furthermore, people don't immediately use Internet dating services when they first become interested in dating. They often wait (for various reasons, but one would explicitly be because they are looking for someone to date,) which probably means that they have not had success with dating IRL first.
I mean, when you first started college, job, or the military (if you're old enough,) did you immediately take to using a dating website? Probably not. I wouldn't have even considered it, because I was in college and was around literally thousands of women my age, with my level of intellect, and were mostly available.
I didn't consider using an online service until graduate school, where I don't have that same contact with people (and thus women.)
I do expect this population to be more "desperate" and more likely to see past some "issues" than those who do not use online dating services (although not all or even most to be like this, but I would reasonably expect that those who choose to not use dating services.)
