It seems cat pictures correlate with longer conversations. They then suggest this means hooking up is more likely (perhaps OkC knows more about the signifiers of hookup than they are publishing here).
Couldn't the opposite also be suggested? Dog pictures mean less talking more meeting up in person, whereas cat lovers are conversationalists?
This entire article strikes me as very sharable though, cats = sex.
[edit]: I initially missed "Ravel is built with love by OkCupid Labs in San Francisco, CA" in the sidebar.
