I applaud the attempt to innovate in the dating world which tends to be solely focused on looks. But sexual attraction is an important part of relationships, so going in blind is inherently risky (from a time utilization perspective). With old school blind dates, your date is friend/family selected so some level of filtering is already done for you. I guess a good portion of dates are disappointing anyway and there a…
For most of us, there's also a very strong mental component to sexual attraction; I mean, sure, there's also a very strong physical component, but I personally think that the text a person generates is a fairly good indicator of how I will feel about the mental component, while dating site photographs, in my experience, tend to be much less representative of how physically attractive I will find the person once we meet. (note, my experience is old, but my experience is that I'm just as likely to find someone way more physically attractive in person than in a photograph as I am to find them way less physically attractive in person. My suspicion is that some people try to present their very best angle, others try to present their most representative side, while others don't put much effort into choosing a photograph at all.)
The other problem is that people make certain, ah, assumptions about me based on how I look. Assumptions that, well, probably will lead you to an incorrect idea as to my personality and values, I mean, more so than usual.
I mean, this is just my own experience. And mostly pretty old experience; I haven't had an online date in rather a long time, but the best online dates I've had were where we didn't exchange photographs ahead of time, either 'cause we met on a medium that didn't really support them, or because we met on dating sites but without uploading a photo. (and yes, sometimes there was, uh, nothing there, physically, but it was always at least an interesting evening.) - my experience was that on photo-focused sites, often I'd get the sort of 'total miss' - where someone would look at my photo and then make what are really pretty reasonable assumptions from looking at me and, uh, I was not at all what they were expecting.
