Dating is like recruitement (in regard to your question). We haven't come anywhere close to solving one-way discovery (finding the right movie for you on netflix, the right app on whatever store, the right game on steam, the right book on amazon). And we're even farther than that at two way discovery (the employeer need to please you / you need to please him, the other person need to be attractive to you / you need to be attractive to her, ...). And self-filled profile are terrible because we don't want to exclude ourselves, so "better keep that for the interview / first talk". So dating site are splitting for the same reason job sites are; to specialize. You want a christian girlfriend, or maybe an asian one, or a rich one, or an educated one, or an artist, or ... Well there is a site for that. It offers a pre-selection that their algorithms are terrible at doing, and self-filled profile are lying about. Eg look at the cupid network, it's artifically split between a lot of sub-sites specialized in a specific kind of love interest.
