Very good point. In addition, so many things cannot be represented digitally in dating/flirting. So much body language and unspoken signals go into reading of interest and intrigue between two people. Albeit my knowledge of dating sites are limited, it would seem being able to replicate unspoken communication is nearly impossible, especially when people are represented as images and text. Sorry for no citations, just a personal opinion based off of my history of reading a limited number of psych and body language books
